Greetings:

Just replaced my spark plugs on my 2014 f22 n20 228i. Pics to follow of each spark plug.

Mileage: 32806

The replacement wasn't all that bad. It took me about 45 or 60 minutes...just taking my time. #4 or the furthest one back was the hardest. So, patience and an assortment of 3/8" u-joint attachment with several different length extensions.

Purchased the spark plugs from FCP Euro. I'd give a step-by-step, but the video quality at the youtube is excellent...on the n20 engine.

Please NOTE: All the extra extensions and u-joint needed to reach most rear plug. It is difficult, but not impossible.

So...I'm just looking for opinions on the condition of the OLD spark plugs?? Was I justified in changing them? Or was I premature?

I've been told that I've been premature in many things in my life, so you won't hurt my feelings...if it goes that way.

Old plugs look good, a little hard to see electrode but looks good.

Thanks for the reply. Sorry for the not so good pictures. For some reason I thought the forum allowed the picture to be enlarged.

Yeah, I agree...the old plugs do look pretty good for the mileage. But, I am happy that I took a few minutes to change them. Peace of mind kind of thing.

Yes, there are several good videos on the utube to view the process of a spark plug change on the n20 or n26 engines. But, I'd like to offer just a couple small but important TIPS/Suggestions.

1. Use the correct and proper thin wall spark plug socket. I used the following...and so happy that I made the purchase!!
14mm 12 Point Spark Plug Swivel Socket - CTA 1061
Part #: CTA-1061

2. Use compressed air (from a can or air compressor) to blow the spark plug area prior to working on engine. Once the coil has been removed...and before touching the spark plug, blow some compressed air down the area making certain that it is clean.

3. Do NOT use anti-seize compound on the spark plug threads. BMW has a TSB that using it might cause a fault code or short.

4. DO use a proper torque ratchet wrench. This is NO time to guess by "feel".


Good luck with your spark plug change project!!

Just a comment on NO Anti-Seize: I have put anti-seize on my plugs ensuring that the 1st 4 threads have no anti seize and ensuring that only a small amount is used similar to the way crytox is used on SS fittings in the aerospace industry . Similarly, BMW will officially say not to use any sealant on the Valve Cover gasket installation -- but MOST BMW techs use HONDABOND HT to keep the VC gasket from leaking and having significant rework. I believe that improper installation is the culprit here and if the anti-seize is installed properly -- it is helpful in removal and mitigates future helicoil installation / headaches.

Is the inner ceramic insulator nose chipped (right by the electrode) on plug #2? That plug looks like it took more abuse than the others, but none look really bad (but the main indicator for this can't show in your pics - how eroded are the electrode tips?).

FWIW, I got my plugs changed as the last act of free maintenance (about 38k miles) and the improvement (smoother idle) is quite apparent, so I do not think you were premature.

I just did this on my wife's 2016 228i with 58k on it. Just curious why you needed all those extensions and joints for #4. I had no problem using a single joint and extension on all 4.
