alright guys, i own IX and i'm currently running e85, boosting at 26psi. Whats a good set of spark plugs I can buy for the IX. I know the VIII and IX uses diff. set of plugs. Hope ya'll can help. thanks!

 

Moved.

 

Everyone will tell you something different. My opinion is stock or IKH's... I've tried them all.... Even the NGK RACE plugs at $40 a piece LOL....

 

i m trying to save some money here..haha..any more suggestion guys??

 

I have always heard great things about NGK and i have been running the NGK 7s in my evo on 100oct for 3 years now with no issues at all. as far as for e85 i think it is the gap that is really different from other fuel...

 

I have an FP Red on E85 @ 30psi and I have been experiencing some real bad fluttering/hesitation issues at low-throttle and after shifting. I replaced my NGK's and now I have horrible hesitation under acceleration that I never had before... Could it be the gapping or something else? The car runs rediculously rich under part/low throttle...

Anyone have a recommendation for what I should gap these plugs at for my high HP setup? Buschur double pumper, 1200CC injectors, 02 dump, basic boltons, stock ECU.

Thanks

 

I have the NGK 8's for E85, runs awesome. I gapped them at 0.25

 

the reason why people re-gap (reduce) the plugs after switching to e85 is because of the higher boost they run after the tune. You can re-gap your plugs if they're still in good working condition.

sounds like most people have the gap set to 0.024 for your boost level.

 

Stock heat range iridiums gapped to .020-.022

 

I'd like to know too, I'm in his boat. I don't think we can gap any sparkplugs since ix's use iridium ones

 

bpr8es gapped at .022 is what i do for e85 with no problems. And they're cheap.

 

I see a lot of VIII replying to the thread. I think the OP is asking about recommendations for the IX that's different from the popular copper NGK's.

 

Guys he has a IX, different plugs than the VIII's.

 

Its been said, either stick with stock, since you have a budget, get the denso Ikh22s. So either NGK's or Denso's. Make sure they are iridium.

 

Me too....but I am running a 1g dsm coil pack...never misfires on this combo no matter the boost I try pushing lol
