In this video I show you how to change the spark plugs on an F30 BMW 340i. This process will be the same for the 440i and any B58 powered BMW. The install is pretty straight forward and I think it took longer to get to the spark plugs than it did to actually change them. Once you remove the engine cover, you’ll notice that the last spark plug is buried under plastic and foam, and taking the extra time to remove that stuff will make the installation of the plugs much easier.
If your car is higher mileage, I’d recommend replacing the ignition coils at the same time since you will have to take them out anyway. Since my car only has 50,000 miles and the coils I was looking for were out of stock, I opted to re-use the original ones.

Have you got your F30 yet! I wanna get one too.

[@Bonfire17]

@@anesuchirima96 I had one! It was amazing to drive. But the premium price tag on maintenance killed it. I had a 335i with some defects. Loved it, but in the end wasn’t worth it with my paycheck.

I just need a quick video to see if BMW did anything weird with their spark plug changing, and even when I had the information I needed, I still watched the entire video. It was chill, and well presented, great editing... everything nice and clean. Really well done man.. I'm gonna have to check out your other videos.

[@EasyTechTrading]

although i no longer have my 340i i still watch the video. make me miss my 340i and how great the B58 engine is.

Great video and with really easy to follow step by step instructions!! Saved a ton of money even having to buy all the tools to get the job done (at least now I have them for future jobs)! Thanks again and keep up the great videos!!

Always happy to watch one of ur videos! thanks for making great content on the bmw

[@duncanj206]

Very nice to see a quality video with the full install and tear down. Please let me know your front strut bar that looks awesome! Doing plugs and coils next weekend. Thanks again for the vid 🤜🏼

[@BadmashKing8]

After having a WRX and STI, I’ve decided to get a BMW. I’ve always been told that they are a money pit so that had me not want them but still have a special place in my heart for BMW. Your videos have assured me that it’s not hard to own one. I’ve always been a huge fan of M3 since I was a kid, it was mostly because of need for speed most wanted lol. I will most likely get the 340i since M prices are still up. Thanks for these videos, your content quality is amazing!

[@Boblib1970]

@@justinbuice I have to agree with Romahn. An indy dealer just quoted me $564 to change the plugs. I know that #6 is tough to get to, but watching this and I see that it's not that bad. I'll be swapping them myself soon.

[@greezygoblin]

Great video as always, I have done routine ignition services on N52, N54, And N55 engines, so this is great to give me some extra insight on how it will looks to perform this service on a M240i B58, which i'll be doing it on next!

Thanks!

[@RASKOwid]

I new the spark plugs were easy on these cars but been hesitant. from my N55 days I heard there was 1 in the back that's a PITA, but really does seem straight forward. I bought the plugs but been lagging, gonna bust'em out. thanks 🤙

[@dracbuilds]

Great video as always! Your effort is definitely appreciated 👍🏻

[@justinbuice]

Thanks!

Thanks to your excellent video, I did my spark plugs today in a little over an hour, and had all the right tools ready at hand. The worst part was putting that damn piece of rubber trim back on (the first piece you took off)!

Great how to video. Thanks

[@Simplyjayski]

thanks bro for the diy!

[@Hyytekk]

Love your chill presentation style, Justin, and your meticulous attention to detail. I have tons of tools but sent for that Wera ratchet set in your links. Sold out on your link but on Amazon at a great price. I'm curious about the very loose fitment, though, onto the wrench. Is that to give you a more forgiving arc in tight places? I saw one review where the buyer also expressed the same amazement and said he was returning his set. Its a bit pricy so wondering if its worth it. Also lack of a tab to reverse the wratchet direction seems strange. Have to flip it over to reverse direction. Any thoughts please. Thanks for your content.

[@aosdnasdmas]

Just in time, just received my plugs and oil from FCP💪🏽

[@justinbuice]

Nice! Good luck! 😁🔧

[@abhisheknilajagi4960]

Hey Justin thank you for the video, i had question do we need to reset any milage meter to register the new spark plugs?

[@gilgonzalez5902]

For anybody that has the older style coils i highly recommend upgraded to the Eldor coils. They are bulletproof specially for tuned applications.

[@SycaShow]

Hear me out, I had a corvette and I loved the pulls then I also got an f30.. and it was missing something running sluggish felt like power wasn’t there. I did my spark plugs 2 weeks ago and heard gapping them to .022 is for stage 1. I did it on my stock and omg.. i can feel the boost of the turbo kick in now! I took a scat pack out today. Highly recommend it And heard it’s best for turbo cars. As the air mixture and fuel ratio.

[@willg6199]

Good video. That said, I busted a bolt on the brace going to 56nm. Are those bolts supposed to be reused?

[@WayoJimenez-hg7lu]

Hey my friend good video i have cuestion waht socket i can used for my 2012 BMW 328i Fwd N20??

[@stuartwickson8535]

Great video, I will be doing this over the weekend. At 4:45 you use a yellow/orange terminal pin tool, where did you get it from?

[@justinbuice]

The orange plastic tool is just a generic interior pry tool

[@moeahmad6800]

2018 bmw 330 use same tools?

[@jaya6454]

Cool 👍🏿

[@bogdanarsene9602]

I like these coils more than the e90 style especially the electric harness where you are not sure if it pushed all the way in or not

[@justinbuice]

I agree. I had a miss-fire after replacing my valve cover gasket on my E90 and it was just one of the coils not pushed down all the way

[@justsaying8254]

What mileage did you change the plugs at? I have the 340iX with the MPPSK tune. I bought the plugs and coils from FCP Euro with their lifetime replacement program at 45K. Before removing the old spark plugs I would strongly recommend using compressed air to blow out any loose debris or liquids in the plug ports.

[@justinbuice]

55k

[@NinoInTheComments]

why no lubricant on the threads?

[@john_does_stuff]

Yo Justin. What mileage were you at when you did this? Im running stg1 MHD with stock motor/exhaust coming up on 45k mi. Have not changed my plugs yet and I'm almost positive I'm running the factory ones. I plan on catless downpipe and running stg2 so I'll most likely do plugs and coils beforehand.,

[@justinbuice]

Mine was 55k. I probably should have done them sooner.

[@iamtrillahd]

Hey with your stage1 and air intake, do you have a catless pipe?

[@justinbuice]

I have the stock downpipe for now

[@arturmuller5598]

Does anyone know the part number of those circular covers at 2 mins in the video? I lost one while washing the car -.-

[@evwhizz]

[@greezygoblin]

The production quality is outstanding :)

[@zendy04]

I have 27,000 miles on my 540i should I change my spark plugs or coils yet or should I wait until 50,000 miles?

[@justinbuice]

You can do the plugs at 50,000. If your car is tuned you might want to do them sooner. I wouldn’t bother with the ignition coils yet though. They should still have plenty of life in them.

[@Codycrispy]

Do you have to reset the engine light after?

[@justinbuice]

You can reset the spark plug maintenance interval using the BC stalk, I should have showed that in the video

[@euvaughntaematheson1961]

Good evening dose the 08 328i subframe fits the 2011 328i

[@justinbuice]

Hey Im not sure. It should fit, but knowing BMW, they might have made changes between that many model years even for the same chassis

[@jambulo]

I believe the strut brace is 56nm + 90 degrees.

What engine do you have? It’s possible to have a code with no check engine light, you’ll need to use a scan tool to see if there are any pending codes
