Plugs for N55 Port Injection

Ozzie335i · 04-18-2016, 02:02 PM

There was a thread here that people went back and forth on the proper plugs for when going with Port Injection on an N55. It came down to the N20 plugs, gapped at .018. The problem is that there was 5 different plugs for the 20. Is there a specific one to use that I need to go with?

I was told they're all very similar, but to go with the newest plugs shown on realoem.com .. They're one step colder that N55 plugs

It looks like you bumped an old thread but the NGK SILZKBR9F8S is listed as a flex fuel plug and is two steps colder. Not sure why but that is what BMW went with.
