I have a Evo 8 that has all stage three mods and a e 85 tune by English, should I be running NGK 8's instead of 7's ? Are Iridums worth the $$$ ?

I am just running BR7ES plugs now at .022" since I am running about 26psi.

I would imagine I am close to 400 HP as I ran a 11.87 1/4 this summer.

TIA, Zach

 

BR8ES would be better at your boost level. I run them on pump and 23# and they haven't fouled yet. I have about 3000 miles on them. I like .024" gaps. But mine is on pump and maybe E85 is different. Ask Warrtalon as he runs 8ES's and E85, I think.

 

Why are you looking to get plugs if your car is running strong as is?

 

Methanol will ruin them, not sure about ethanol e85

 

Most flex fuel vehicles use iridium plugs.

 

the difference between the two wont be noticeable

 

Speedster: The difference between the two whats will not be noticeable? You're post whoring so as to build up your post count, and thus, be able to run an ad in the, "For Sale Forum". Or am I mistaken?

 

I'm running BR8ES with E85 no issues
