Hey Jake! Curious if you know the production date of your 335i and which DME it came with. MSD version 80 or 81. I guess the 81 was implemented mid ‘08 and the 80 prior to this had problems with mosfets with upgraded coils. Just curious if you’ve had any problems with your DME if you have the 80. Thanks man!

[@TheRebuilt1]

Very nice, I just started working on a friend's X5M BMW for the first time. Have you considered a leak down and or compression test on this car

[@jake_spence]

Nice - I see no reason to do a leakdown or compression test on this car right now, so I haven't done one.

I like the BMS cowl filters.... however, when I installed mine, every time it would rain my windows would fog really bad. I left them on for about 6 months. never failed, always fogged. switched back to the stock cowl and my windows haven't fogged once. only complaint lol. thanks for the quality videos man

[@jake_spence]

Yeah, I've heard of that happening. Happened to me like once, but never again. Not sure why lol thanks for the support tho!

[@jmp6534]

Hey Jake...iv seen some bad reviews on Amazon with feeler gauges.. Regarding not being accurate, can u add that link to the one you bought.. that you used from Amazon. Thanks. Didn't see it on the list. Also in actually running stock plus with fbo. E50 flex fuel.. not having any issues. I change then yearly. But im going to update when I go inlets and outlets any day. Thanks man. Keep up the videos

[@jake_spence]

Hey man, this is the feeler gauge I use: amzn.to/2HJoLfn - sounds like you've got an awesome build going on!

[@murk1352]

Precision Race Works has the best gap tool! Its just like the one you were using but fits both 12 & 14 mm spark plugs & has a gap opener in the back. It's pretty handy. I think it comes with the good feeler gap gauges too...👍🏁

[@ASSASYN187]

you da real MVP. Everything BMS is overpriced.

[@murk1352]

@@ASSASYN187 That’s why I get PR!

[@Trusty335is]

Hi which spark plug socket do you use? I bought one that was supposed to be 12 point thin wall but it wouldn’t fit so bad to grind it down more to make it thinner wall and fit. I’d like to purchase the correct tool. Thanks!

[@BIMMERZEITT]

Nice work Jake! I just finally posted up my version of this DIY in 4K on my channel. One interesting thing to note is that the BMW workshop manual specifies a flexible extension or universal should be used with the spark plug socket to prevent potential insulator damage. In the real world it's not really necessary if you're experienced like you and I, but thought it was worth mentioning in the DIY for others.

[@jake_spence]

Nice! I'll have to check it out to get another take on this job.

[@BIMMERZEITT]

@@jake_spence by the way, the 1-step colder NGK's you recommended with the new coil packs and the car pulls soooo hard compared to before!

Glad to hear it man! I think that's the perfect combo. What's next?

[@BIMMERZEITT]

@@jake_spence I have an intermittent 30FF code when I drive hard. Some days no code and it is pulling hard. Other days it cuts power and throws the engine light... any ideas?

[@jake_spence]

Boost leak somewhere or the turbos are finally starting to give up.

[@aboynamedtoni]

question; if my car is already tuned on whatever sparkplugs are in there, but i dont know the gap size, can i just check the gap size on the old ones or do i need to just find whats recommended and then re-tune my car? i dont know how specific the new ones needs to be gapped to make sure the tuned car is running the same. (im an n54 single turbo)

Thank you so much

[@jayspies9860]

Subscribed. I just picked up a 50K mile 2013 335is vert and want to do the plugs/coils and the walnut blast per your videos. Quick question - can you use 1-step colder plugs without mods? I want to do maintenance first, mods second, but I don't want to have to do plugs twice. Thoughts?

[@jake_spence]

Hey, welcome to the channel! 1-step colder when stock is fine. The plugs I just installed are 2-steps colder and I'm still stock. You will be fine, no need to do them twice.

[@jayspies9860]

@@jake_spence Perfect, good to know!

[@erizzle67]

Just did mine. Had a cylinder 3 misfire, swapped coils with #2 and the misfire followed. There was definitely some quirks to this job. That strut tower brace was really in the way so I had to move mine. Most importantly though the stupid plug socket I got from ECS wouldn’t fit any of my extensions. So I had to literally hammer one In and now that’s my permanent BMW plug extension. Also, I was also surprised that the coil tubes were at a slight angle to the plugs. The socket and extension don’t go perfectly straight in. I also had a scare with #6 - plug was WAY too tight. That’s what you get with a mystery used car though I guess. I’m an old school shade tree diy guy, haven’t messed with older cars in a long time though, 20 years? Was surprised that anti seize was NOT recommended. Back in my day in the 1900s anti seize was a must. Parts store guy had never even heard of it. Glad I googled it.

[@BMWflowrider]

Nice video Jake! Do you have any feedback to the Ingnition Coils from ECS? What is the difference to BOSCH and DELPHI? thanks bro!

[@jake_spence]

The Bav Auto coils I used in this video are still working great to this day. However, I've also used BOSCH ignition coils in the past and they worked good as well.

[@BMWflowrider]

[@lpa187]

Great video like always bro.. Just one thing idk if it's because I'm as little ocd.. But when I do plugs when I drop them in, I usually rotate backwards (off) until I feel it drop into the threads.. I feel that ensures of any cross threading situation.. Can't wait to see the mods done..

[@jake_spence]

Great tip! I know that if it's cross threading, it would have resistance. But this is a great way to be 100% sure that they're not going to cross-thread. More mods coming soon!

[@jake_spence]

I appreciate that! Thanks for the support, without comments like this it’d be hard to keep grinding.

[@angelbecerra3374]

What do you think of the coil packs? Why not go with precision or the r8 ones? Precision did a test on the "okada" performance ones and turns out they're exactly the same.

[@jake_spence]

So far, so good! I got a deal on these ones, so I wanted to give them a shot. I like that they're drop-in replacements with no wiring or coding needed. If they take a crap, I'll make an update video.

[@BMWHOBO]

I have 2008 335xi coupe with an upgraded FMIC, DCI, and MHD stage 1+ tune. I made 362WHP on a dyno jet. I bought NGK 1 step colder plugs because it was time to change my stock plugs out (no misfires on stock plugs), I gapped them to .0275 (Factory gap), do you think I should have gapped them to .022 (high boost application). Car runs great with factory gap, just wonder if I would get a little extra power with the smaller gap.

[@jake_spence]

If you aren't getting misfires or timing corrections at 0.0275", keep running it. You usually want the widest gap possible without ill effects.

[@dicksuedkamp]

Have you done a compression or leakdown test? Looks like it was running rich at a minimum, potentially have some oil making it past the scraper rings...

[@jake_spence]

No, I haven't. But that's a good idea before I start modding it like crazy. I'll add it to the list of things to do before installing mods.

[@joeys3580]

I’ve been very interested in getting a N54 135i for awhile, if I’m buying one with or without some basic bolt on’s- what’s a good number to budget for at the beginning for maintenance to keep the car healthy? $1500-2000? Such as the coils, plugs, etc

[@jake_spence]

Are you doing the labor yourself? If so, you'll save a lot of money. I would budget ~$500 for oil change, spark plugs, ignition coils, and walnut blast parts. ~$1500 for NEW injectors if needed. ~$500 for water pump and thermostat if it has never been done, do it when it dies. Turbos could be fine, but if they take a crap, you can get stock replacements for cheap or upgraded ones for a couple thousand dollars. A few hundred bucks here and there for gaskets, etc. Oil filter housing, valve cover, oil pan gasket, etc.

[@joeys3580]

Jake Spence thanks for the reply! Yes I plan on doing the work myself. I’ve had an e46 and e36 m3, and am looking for a more modern car with some straight line speed. That’s a good answer. Are there enough resources to know what needs to be replaced when the car misfires, throws a code, etc? After doing these maintenance items over the course of 6 months or so.

[@Gendo3s2k]

I'm FBO MHD2+ (DP, 5 inch stepped intercooler, DCI, Inlets, Charge Pipe) Index 12 injectors, new stock Bosche coils and Spark plugs. I'm getting misfires and cylinder deactivation when I give it more than half throttle. Is this because I need colder Spark plugs? The online guide suggests the -1 colder NGK plugs for FBO, but Jake seems to be suggesting -2 for what looks to be a similar build?

[@jake_spence]

You can do 1 step colder or 2 step colder. I went with 2 step colder because the 1 step colder plugs were out of stock everywhere. I can't say for sure that you're getting misfires because you need colder spark plugs, but it's worth bringing your ignition system up to par.

[@tristanrediger]

Eldor coils feel like they're twice the weight of the bosch ones. I'd give those a try if you wanna keep budget in mind

[@jake_spence]

Interesting! Good to know.

[@HeathHerring666]

I have the n55 f30. I want to upgrade my ignition coils. Would you recommend these bavarian ms coils over precision raceworks, cosmos, and ignition projects coils? Looks like you have them in both your cars. Just wondering because the bavarian ms coils are priced fairly where as the others get pricey. Thanks

[@jake_spence]

I liked the Bavarian Auto coils because they're a drop-in option. But if you want the best upgraded coils, I'd recommend Precision Raceworks.

[@bmw_for_life8902]

[@jake_spence]

I’ve had them on my 135i for years without an issue. Driven in rain and snow.

[@DaEverything1]

i have an n54 with the bosch sparks but want to get the NGK ones instead.. it says N54 applications require the spark plug gap to be changed to OE 0.7mm (0.0275″) or 0.56mm (0.022″) for high boost.. what does plug gap mean and how would I change it to 0.0275” or 0.22”??

@@Kipitrl sounds fun! I've come to terms with when modding these cars, you'll get some smoke on decel depending on your setup.

@@jake_spence ya especially in m mode when you get the pops and burble.. im still torn between pure stage 2 hf or doc 6266? Whats your opinion since youve been running doc for a while? I like the quick get up and go on the streets the twins have.

[@jake_spence]

@@Kipitrl if you love the down-low power for around town, you'll probably want to stick with twins. PURE is good. But I love my Doc Race 6266 setup. You need to rev it out more, but when you're in power it pulls so much stronger than twins. I had MMP S3 before the single and would choose the single all day.

[@ianc2918]

do you recommend .020 or .022?

[@bulkhogan5]

Injectors are expensive. I had index 1 in my car. They didn't leak, but definitely caused me some issues with mileage. Be careful if you find some used ones because you have to get new o-rings that seat into the head and that requires a special tool

[@jake_spence]

Thanks for the heads up on the o-ring... I forgot about that. I'm looking at used injectors but might just bite the bullet on some new ones.

[@BTSyaya]

Curious as to why you would go with the ecs tuning/bav auto coils when fcp sells the eldor coils for cheaper? I skipped ahead in the video so maybe I missed a sponsorship or something.

[@jake_spence]

To be transparent, I was offered a deal on these coils and that's why I wanted to try them out. But I would never use something that I don't believe would be a good fit. Bav Auto carries a good name so I trusted giving them a shot, so far so good.

[@BTSyaya]

Jake Spence love it! Thanks for being honest. Nothing wrong with that at all. Always good to know what products are good regardless of where they come from. Thanks for the video mite actually have to get one of those spark plug tools.

[@garrettwash889]

I'm new to the BMW world, so this may be way off, but I always put a little dab of anti-seize on the spark plug threads. Is there any reason that you don't?

I've just never been taught to do that, but I see no problem with it. As long as it's only a little dab.

[@bmw_for_life8902]

I’m running those coils in my 135i n54 pure stage 1 turbos and I think they might be causing a problem also when I installed them I noticed one I pushed them all the way in they wound stay all the way down might be my problem

[@jake_spence]

Yeah if it won't stay down, that's an issue. I've had these installed since I uploaded the video without a single issue. I'd make sure you aren't dealing with an installation error first.

Fyi: Bosch 9620 are my choice because double iridium and 7yr warranty at Oreilly. 😁 9620 cross over to the ngk spark plugs everybody uses.

At 10:53, what are the circle "plug" looking things to the top left of the coils. I have oil in one between my 2nd and 3rd coils.

Hey Jake - just installed a set of 2-step colder plugs gapped at 0.020 per BMS specs and running MHD Stage 1+ then started havin misfires. No issues with OEM plugs. Any recommendations or thoughts on what could be causing this. Im in WA with 92 being most common.

[@jake_spence]

That's weird. Are you sure the gapping is accurate? Are the plugs tight (torqued down)? I've seen them come loose after a few pulls. Did you change coilpacks? You could try swapping plugs back one-by-one to verify it's the plugs.

[@kylehanaway1613]

@@jake_spence thank for the quick reply Jake. I'll take your advice and start swapping plugs and verify gap is correct. Could these plugs be too Cold for my setup possibly? Really enjoying your videos btw. Thanks

[@jake_spence]

@@kylehanaway1613 they shouldn't be. I'm using the exact same plugs in my bone stock 335i, same gap too. Glad you enjoy the videos!

You know what's crazy is the I have the same coils and ecs tuning is saying the performance coils you have will not fit lol you thoughts on that.

They should fit. Something must be entered wrong...

Where are you located.lol. never mind. Put my glasses on. Let me know if you want a free stay in North Jersey just across from NYC in exchange for some tuning

[@electricamish4711]

actually you can gap the 3 prong ground....I had a missfire on a cylinder, even after changing plugs...when I checked the new plug again, it had one prong that was nearly touching the center electrode, i took a pliers and pulled that prong out to match the other 2 and missfire went away...shouldn't happen , but there ya go.

[@faithrife5027]

I would highly recommend some anti seize on those plugs going into an aluminum cylinder head....😁

[@jake_spence]

Great point! Usually they have anti-seize pre-installed but since I bought these plugs "lightly used" the anti-seize was worn off and I forgot to re-apply some.

[@camluczi]

How about not? Not recommended since they can throw off the torque. These are sensitive to torque because of the direct injection

[@draytonPW]

What's up with cylinder 1? I just changed my coils and plugs because of misfire codes in 1-3. Cylinder 1 plug looked just like yours.

[@channingleiser2409]

Did you gap properly?

@@channingleiser2409 Oem Bosch 3 prong plugs, "ungappable."

@@draytonPW Is your car stock? I’d recommend NGK plugs. If FBO then one step colder and if FBO+ and using E85 I’d recommend two step colder. Same goes if you are single turbo or upgraded twins.

I get hiccups at idle a slight misfire but no check engine and sluggish power. I changed my injectors replaced with new seals Changed spark plugs but didn’t change ignition coils. But I get no codes? What could it be

If you haven’t found a solution, Did you check if your intake valves are dirty? Had a similar issue and that pretty much resolved it

Fcp euro with their lifetime replacement warranty is the best route .. but I’d say bms too if they sent me parts. 💯

[@seanboyd5494]

Jake, not to be offensive but you need to read, understand & comment on dimensions such as the “Feeler Gauges” you were using in this video. You stated you were using a “200 thousandths gage” when in fact you had a “20 thousandths gage”. I am a professional inspector and have inspected parts for cars, trucks, military vehicles and components on the international space station so I have some history in this. Think of it this way, a human hair is approximately “4 thousandths of an inch (0.004)”; an 1/8 of an inch is 0.125; a quarter of an inch (1/4”) is 0.250 or called out as 250 thousandths. You mentioned 200 thousandths which is 10 times bigger than you wanted. Hope that helps you as you have helped me to work on my sons car.

[@MalindoWe]

Used an impact and pulled them out without touching a ratchet. Plugs were never changed before

[@ebeliohernandez5895]

what gap size for a single on wastegate 🤔

[@jake_spence]

Depends what kind of ignition coils you have. But I'd recommend within the same range of 0.018" - 0.022".

[@ebeliohernandez5895]

Jake Spence stock for right now getting Precision raceworks next!

[@Gomepez]

Can’t say Index 12’s lightly these days they cost more than the car did.

[@bornfree180]

Never seen an after market coil do any better than the a “quality o.e.m “ coil I’ve seen tuners that had more bad things to say than good on this subject ... just my 2 cents

True, I think the only upgraded coils for these cars are the Precision Raceworks.

[@anthonykosters7874]

As a fellow e90 n54 6MT owner with about 30 grand in the car in mods. There is no way you are making 10s with stock turbos and factory inlets. Even with TFT inlets, you'd still blow up your turbos first.

[@jake_spence]

It's a tall order, for sure. And I never said I'd do it without inlets. It's been done before and with enough weight reduction (and maybe a little nitrous), it can be done again. PS: I've gone 10's in my 6MT 135i with more than $50k invested lol.

Jake you are shifting WAY too late for stock turbos. Serious drop off after 6250rpms so shift autos at 6k. -og n54 guy

[@jake_spence]

Yup, I'm aware. Just wanted to rev it out for consistency sake so I can compare mods without altering other things such as shift points. But for a true best result, I can shift faster until I get inlets!
