BMW N55 Spark Plug Replacement - DIY, Diagnosis and Repair

[@madminute7598]

Just randomly read about FCP Euro and their warranty. Fantastic team, fantastic terms. Just made my first order this week for spark plugs and coils on my n55 (including the torque wrench and socket) - and I didn't even know they did instructionals. I will recommend them to everyone. Thanks, FCP Euro.

[@NHILLproductions]

Thanks. Great DIY video. I used your DIY to change the valve cover on my 2011 535i. Took me a while, but your video was a TREMENDOUS help! Keep up the great work!!!

[@gabbyprod]

Great video! Just spent a couple hours doing plugs and coils with my son on his 535iX. We kept coming back to this video and referencing it. Job was easy, especially with the step-by-step instructions on what to remove in what order. Thanks, FCP Euro!

[@nicholasvollaro4727]

Just did a spark plug change on a 16' 640 N55, to get to the 5 and 6 plug you need to remove a bracket directly over 5 and 6 that holds two electrical connectors and the big plastic bracket that cradles wires going over the back of the engine to move it to remove the foam insulation as well also required to do 5 and 6. It seems that was done before you started the video. The fasteners on the pax side are a PITA. Could have referenced that.

[@daslothmc3910]

Dude thanks I’ve spent so long trying to find the other two coils

[@jackmiller4510]

Yes bro I’m stumped on 5 & 6 cause they don’t even mention them in this video 😂

[@rpgrayso]

Thanks for the tip! Just did the same (removed bracket, just the passenger side, and foam on a 2017). Number 6 plug is a real challenge. I ended up using a short extension and a universal joint on the spark plug socket. The universal joint allows you to "fold" everything down into the spark plug well as you have very little vertical clearance.

[@caddyak93]

Helpful Tips: - Buy a LOCKING ratchet extension. The first time I tried this, the socket got stuck on the plug and I couldn't get it out. If I had a locking ratchet extension it would have helped. - spray some P'Blaster on your plugs and let it sit over night, if they're stuck. Mine wouldn't budge at first, but came out after soaking overnight. Thanks for the video! Super helpful

[@John-qc1zv]

That is a very cool tip, will buy that.

[@gianni_schicchi]

Thanks for mentioning the TSB on the corrosion. I have so much, I was worried. It did flake down onto the valves a bit but I blew it out with air. Thought my seals were bad or something but everything looked good and the coils "popped" with pressure taking them out. Weird moisture can get in. New coils seem better protected with rubber though.

[@RaulRincon28]

how do you know how tight to tension the plugs/what tool do you use to measure tension. also how do you "gap" plugs? sorry, newbie

[@fcpeuro]

Hi, Raul. No need to apologize! We're here to help people learn! You use a torque wrench to tighten things to a specific torque setting: www.fcpeuro.com/products/3-8-drive-micrometer-torque-wrench-30-250-in-lbs-gearwrench-85061 Gapping spark plugs is setting the distance between the tip of the spark plug and the electrode, you can lightly tap the end of the plug to close the gap, or use small plyers to open the gap. Properly measuring the gap can be done with a simple tool like this: www.fcpeuro.com/products/spark-plug-gapper-cta-manufacturing-cta-3235

I know that Spark Plugs has gotten better and last longer due to the "platinum firing tips that dont erode and with the Advancement of Technology , as older standard plugs use to in the 80's that needed to be change fequently. but why is these plugs ( platinum ) the best plugs changed this early,like 60 + thousand miles ?? i have seen them go 2 hundred and 3 hundred thousand in other types ofvehicles, without much erosion or wear on the tip (centre Electrode) so why is BMW Recommend to change them so frequent ??? i guess $$$$$$. any input please ty

Hi, is it ok to use a one step colder ngk plug on a completely stock engine? Will it hurt anything? Thanks for this video.

[@fcpeuro]

We always recommend running OEM equivalent spark plugs if your cars engine is not tuned. Colder stepped spark plugs are more specific to tuned engines.

[@davidzaph2501]

@@fcpeuro thanks very much, I'll be ordering the ignition kit from fcp actually and changing the plugs, coils and valve cover all at once and doing it with confidence thanks to your videos, it's really appreciated.

[@KingMcAl]

One step colder spark plugs would most likely leave you at risk of reaching soot fouling when doing many cold starts. The Center electrode has to reach temperatures above 400°C to de-carbonize. Although, if you drive a bit more aggressively than the normal person you might benefit from colder spark plugs. Also another risk with one step colder spark plugs is lower power combustion stability. Although NGK says that their HR8 is equivalent to Bosch HR 5 I think, NGK heat range 7 might be the more OE type heat range, or for instance DENSO heat range 24 would work as well. Also an FYI, always use a torque wrench when replacing spark plugs. The ceramic is very brittle and sensitive to overtightning. The ISO standard for M12 x1.25 spark plugs in an aluminum cylinder head varies from 15-25Nm. The maximum tightening strength resistance of spark plugs are usually measured from above 35Nm, never go above this on M12 spark plugs, stick to the ISO standard (15-25Nm). Also, do not relighting the spark plugs if they have a compressible washer/gasket.

Great video, that corrugated hose with the 4 clips, what is that, I need a new one. Thanks

[@stephencannon3140]

In addition to only replacing one cylinder at a time one more trick and again just me..... As you open the box and install the new plug, place the used plug in the same box and mark 1-6 for the cylinder number. I do that and place all the old plugs in the boxes and if busy you can read the old plugs at a later time. Also allows you to compare plugs with burn charts and isolate any problem plug to a specific cylinder. Simple and only a few extra seconds. You could even go so far as marking the boxes with cylinder number before removing the new plugs from the box. As for checking gap....despite what the box may say always verify proper gap before installation. The box can get bumped or jarred during packaging or transit to the store and even the slightest bump could throw gap off. Having had another vehicle with the 14mm spark plug sockets before I will advise be EXTREMELY careful when loosening and tightening the plugs. I had one that felt like it broke in half and was expecting to pull half of a plug back when I used the magnet to remove the #1 cylinder plug. Fortunately it came out as one piece but be very careful. There is not a lot of tolerance and plug tight and breaking can be a matter of 1/16th of a turn. Use Torque wrench for this one. As with pretty much any spark plug removal don’t use air or electric tolls to break torque. Note regular ratchet/socket to break torque and then the electric ratchet. Thanks FCP for the video

[@jasoneyes01]

These guys are cool at FCP Euro. Advise for newer Bosch spark plugs.. Be mindful of loose aluminum on steel screw on terminals. They tend to come loose with heat cycling and will cause your ignition coils to overheat and fail. Possible cause MOSFET failures in DME. Bosch decided to crimplock them on the thread without loctite. If your racing or looking for long term reliability please pay attention to this.

[@fcpeuro]

If you aren't having any ignition issues at the moment, you should be fine for a little while longer, but if you want to avoid any future issues, you can certainly replace them now. If you do start to develop any misfires, then replacing them all at once would be the best move.

[@jdsilvaca]

The V8 is a bit more difficult. The rear plug on each cylinder is a pain to reach. Also, makes sure you have the correct coils, of you are replacing thoses as well, and hell, you might as well do them. If you have the wrong coils, they wont plug in correctly, and even if you do get them installed, your BMW won't start. It will crank, but it won't start. So, pull a front coil, get the part number off of it, and order them that way. Don't just the parts store, or even FCP, Pelican, ECS, etc..... Check your part numbers!
