Hello guys, wich plugs do you guys run with? i will be running E85 and around 600 bhp

Thanks in advance

 

I run BPR8es gapped at .020 with a sparktech ignition.. its taken upwards of 687whp dj at 42psi~ with no blowout.

you have a evo 9, id get the stocker densos but 1 heat range colder iridiums and call it a day. be careful when you gap them u can destroy them easy.

 

i run BR8ES gapped at .024 with a buschur COP ignition. 700+whp emery @ STM's mustang dyno

 

I run the Denso 1 step colder for Evo IX's stock gap, IKH22 I think the part number is. I'm Over 750.

 

I was wondering the same thing. How about NGK BPR8EIX or BR8EIX?

 

Would have never thought to run a colder plug on E85, still not sure. The fuel is cool as it is...

 

you may lose some snappy response driving around town with a colder plug on e85, but its worth the safety WOT.. no matter if it can run cool or not you dont want to find out what happens if you run to hot of a plug on e85..

 

i dont see why not. denso or ngk are both proven brands.

 

I run the BPR8EIX (iridium version of the BPR8ES)...

 

this one ? http://www.amsperformance.com/cart/n...ug-bpr8es.html They seems wery cheap??

thats because they arent iridiums. you can get them at any local parts store and they are almost always instock. you will have to replace them more often depending on your setup. i get 8 at a time.

 

why is everyone recommending him evo 8 plugs when he has a evo 9....lol
