Stock iridiums should work fine. Maybe one step colder if you're running 25+ psi.

Not quite sure what kind of effect e85 has on plug selection, but I use ngk br8es with my FP Red at 30 psi on pump with no problems

I am running the NGK BR8EIX, i am running on 93 with a FP green @27psi with all bolt ons. They have worked good for me but i cant speak how they work with E-85

i get them from the site below (Extreme psi)

YOu know I don't know how trusted my faith on this fable is. I still have the stock plugs in my 2011 EVO and have been running e-85 for two years now with no issues. Don't get me wrong it is time for a tune-up and change them but swapping them out after every oil change? I don't think so. Let me know your feelings on the matter. I don't think it has been luck either. Arizona

My Ngk br8es plugs gapped .020 are working fine on e85 at 30 psi. Still on stock coils and plug wires with an fp green turbo. Priced cheap too, a little over $2.00 per spark plug.

I've run BR8EIX gapped to .50mm and BPR8EIX gapped to .60mm both on the same car, running 95oct and 22psi boost. Both run flawlesly up to 8100 rpm.

I have the NGK Laser Iridiums (ILFR7H) which is the OEM heat range for the Evo 9. I didn't go with a colder plug because I'll be running E85.
