What spark plugs & gap ??

[Blackedout]

04 cobra with F1-A pushing 25# boost going to be running E-85.... Thanks for the help

I have zero experience with that combo or with E85 so take this with a grain of salt.
I would think you'd want to run a pretty cold plug (maybe a NGK TR7) and gap those
babies down to 0.024-0.025" or so to prevent blow out.

Any other input... or is the TR 7's a good start ??

I would use an iridium no matter what you choose, the copper plugs are notorious for idle problems.
