I have search around here but I could not find a certain spark plug that people are running with E85/93 fuel. If anyone can point me on the right direction, I certainly appreciate it. Im also running 33psi on E85

The ones I've seen that are at a moderate price have been:

stock: ILFR7H (NGK)
1 step colder: IKH24 (denso)

Thanks

 

I'm running 28psi on stock turbo with E85 using stock plugs straight out of the box.

 

Good to know! Now if I could find e85 anywhere near me.
