The OE NGK plugs are hard to beat, esp with stock tune.

Look into. NGK part# 95125.
This plug looks promising.
It has a flat tip at the end.
Supposed to be better. For turbo cars.
I ordered a set. I'm a step colder for a tune at 8.
But these are heat 7 and are NGK ruthenium
Sat they help for better a better combustion burn and no pre detonation as turbo cars have this phenomenon
Of( pisp )
I've been obsessed with this ever since I knew if we push our cars hard every day you can definitely blow your engine.
Due to knock higher than -10 thats bad.
After my Carbon clean. I'm getting -0.00 and open throttle race hard. Got -2.25 and next hard run. -0.00 knock. With step colder racing plugs.
Before the carbon clean and stock plugs with tune.
it was -5.25 open throttle on all cylinders.
Things got better with molygen green 5w40 oil as it has additional additives to burn deposits.

and the oil keeps cleaning thats another discussion.

I'm hoping this will cure less knock not major but no knock is better.
As of now. There isn't much reviews I'm swapping them out when they arrive.

Ty for posting this. I definitely chimed in. :D
