What plugs for gn-1s and e85 ?

[Trbobuick]

Ive searched all the threads i can find but it seems noone is running gn-1's with e85 ?

If so what plugs are you using for 25psi and 24 degrees of timing ?

Same plugs I use with gas, NGK TR5's for the GN1's.

Some guys have had to gap them down a bit for high boost on E85 (.020-.025") but every car is different. I run about .028".

Will E3's work out Eric?
They've been great for me and others so far.

E-3s are great plugs to use for E85 or gas. No gapping required...:biggrin:

Diamond Fire makes them. I've personally run them up to 25 psi with E-85, you do not gap them. My friend has run them at 28 psi on race gas no issues. They are good plugs but a little expensive.

Who sells the E-3s? Never heard of them before.
