Spark Plugs for Turbo

[baguete]

Hi guys, what plugs are you using on your K11 turbo engines?

NGK BKR8e-11 , but only as a precaution. They work quite well against detonation.

I think my ngk plugs just a grade cooler than stock running 10psi

Bkr6 eix I'll always use them out last denso and hks (which are basically the same)

Yipes, I run 7's on our N/A setup and even they are slightly hot on the ground straps but they don't foul up on the light stuff, so are a good compromise.

Grades seem to vary too from plug to plug, so Pulsar plugs maybe an option to start with.

NGK a grade colder iirc...cant find the plug box (put them somewhere safe lol) or id give you a 100%, and again iirc with the gap made slightly bigger. So far so good

Too hot i think? You should get some more colder plugs, grade 7 or 8...
