Stock turbo full e85, currently using ngk 97506's. Need to change plugs and wanted to know if anyone has experience with better options for plugs.

cheers

I have had good experience with simply the ZR-5-TPP-33-S plugs.

In my experience, do not gap them smaller. E has a slower flame front and is a much higher concentration of fuel. If anything, make sure your spark dwell is a bit longer and you have good coils.

I hope you have done your research, fueling wise, on what you need to run full E85. I don't see the appeal on stock turbo, but I will not pick apart your choices - I will just offer advice.

Just got tired of mixing so I got port injection. Spoke with my tuner and he says ngk 97506's are perfect at .018" gap
