Just tryin to get ready for my E85 tune here in a few days and was wondering what plugs I should run..... Its a 2003 Evo 8, FULL, FULL bolt ons, 272/280 cams, IX turbo, blah blah blah. On 91 pump at 24 psi its doin 370whp with approx. matching torque (dynojet), and figure the boost and E85 should add another 50+whp/trq. So what does everyone think? Im thinkin I should run a copper 8 heat range plug, but not sure which one, and the gap...... Any suggestions would help, thanks

 

im on e-85. i have copper spark plugs gapped at 20

 

one step colder ngk's for the evo 8... they are like brp8es or something..

 

ask your tuner ahead of time. im sure he will tell you what he thinks you should use.

 

br8es plugs might be close. they are stock number 5422 if you need to get some

 

br8es or bpr8es? Whats the difference?

 

One is a protruding tip and one is not.

Go with the BR8ES.
