im about to get a E85 tune on the 14th and was wondering what spark plugs i should put in the car. mods are intercooler, upper/ lower I/C pipes, TBE, AEM tru boost. im going to tune it at 28-30psi. should i get a step colder or go with stock plugs with a smaller gap?

Stock...I've been on E85 for three years, using stock plugs (gap .024") at 28psi with no break up.

ask your tuner

Ive been running NGK Copper plugs gapped to .027 and have had great luck. I change them about evey oil change. And since they're only a few bucks a piece, they're very economical.

My car is also a track car only.

But also be sure to ask your turner as well.
