Bosch vs NGK vs Other Spark Plugs

GTBrandon · 02-20-2017, 09:38 PM

Since I am approaching 40k on original spark plugs, as well as going FBO w/ a tune, I figured it would be a good time to do spark plugs. I have been told by some to stay stock, and have seen others on here recommending going colder (not sure what that means) or gapping the plugs, or simply using something like a S55 plug. Anyways, what are your recommendations and personal experience regarding which plugs to use and why?

Hey brandon get 2 step colder if you're going to run E85, DP or/and Stg2+ Tune
You can also ask your tuner for tips.. see what they suggest for their tune.

In my opinion .018 -.022 is the most common used

What about without E85? I do not have access to it where I live, and don't plan on running it anytime soon.

Was reading on a thread for 2013 PWG cars - NGK 5992 (1 step colder should be fine) .022 (but for E85 applications get 2 step colder)

For 2014+ late models turbo EWG cars - NGK 97506 (2 step colder) found in N20 & S55 motors from factory.
Suggested for higher boost E85, water/meth injection, and/or upgraded turbo gap to .020 is suggested
