Spark plugs for N55 Engine

Evo23IG · 07-19-2014, 04:07 PM

Hey guys, I was wondering if NGK makes spark plugs for 2011 BMW 135i N55 and whats the part number? I was at the dealer and they want like $25 a piece for them. The car is stock.

Another question about the N55 plugs. Are they all ones with single post and the N54 has the 3 posts? Have seen both and just wondered the difference.
Thanks!

I'm pretty sure all BMW engines have 3 grounds (posts) on the spark plugs. But 1 will work fine, it's worked for how many years on how many other vehicles?

Seems no one is having issues as long as they are gapped properly. 0.025" should work for a stock setup.

Heres a thread for spark plugs that'll fit in the N54/N55:

You'll probably have a rough idle for a few days until the computer works things out.

The N55 spark plugs from the dealer only have a single ground, where the N54 plugs have 3. I changed mine last fall with 22k miles on the car.

That's what I wanted to know. But some places list the ones with 3 grounds as the proper plug for 2011 135i. ZGR6STE2 is the Bosch number listed by Bavauto and Amazon and a couple other places as the plug for virtually every modern BMW. Rockauto lists ZR5TPP33 (single ground) for 2011 135i.
I should probably just get those and return the ones from Amazon......
