I recently purchased an o3 Evo 8 and need to change the spark plugs, but i am not sure which ones to get. I have seen many arguments for and aginst iridium as well as copper, and different heat range, i would like to go ngk. It has aftermarket cams, TBE, EBC, what do you think is best.

 

ngk bpr7es or br7es

part #: 2023

You can find them at schucks for $1.99 each. I always gap to .022 I run around 25 psi on 92 octane.

 

+1 for ngk bpr7es or br7es....... i keep mine gapped at .026

 

^how much boost you running? I would go down atleast to .024

 

bpr7es should come pregapped, drop in and drive.

 

I just went through buying plugs for my 03 evo i just bought and i just picked up 16 of them . . . i like to have stock.

 

more like check them, regap and then drop in...

 

so then with a all around stock car would that be the same suggestion for spark plugs....or any different since there isnt anything done yet....


what about gapping the plugs running stock boost now and maybe bumping it up sometime soon?

 

^id say run the bpr7es's at .024 at stock boost.

 

word.....thanks....

then what you do think adjust gap once the boost increases?

 

yes, .022 at 25+ psi has been good for me. I change my plugs every oil change, cause they are so cheap.

 

Aye, wish I could do that with mine, damned evo9's.

 

^yeah, but you got mivec, so i think we're even

 

once again thanks


im sure i will be thanking you all more and more as time comes

 

more s-hite to break
