NGK BR8EIX are a bit more expensive but another great option. Probably my #1 recommendation.

In regards to 8's is do iridiums or coppers seem to work better on e85? (stock heat range if you do)

Wow, I learn something new every day, thx Ted and Jerry.


Just so I'm understanding you two guys correctly, since I have an Evo 9, you are suggesting to go with LFR7AIX over ILFR7H (stock evo 9 plug part #)? I couldn't understand exactly the reason for going with the "Evo 8-like plug" on the Evo 9..

I've been using HKS heat range 8 plugs for a while, and haven't really noticed much issue after getting the latest speed density patches from Aaron, but I did get an occasional stumble so I'm going to try the 7 range and report back when my car is back together -JM

Took the car to work this morning. Missing like crazy. I'm hoping its that I kept the
stock plugs that were already misfiring. I'm thinking that's what it is cause the non Cdi helped alot, when installed on Saturday. So one more time, evo 9, e85. What plugs

Iridium's seem to work better/longer life on Ethanol fuels. Coppers work great on Pump and race fuels.

Been running coppers on E85 since the spring, without a hitch. I use both, BR8ES and BPR8ES.

This is interesting, I just had a set of IKH24's I was going to install, but figured Id send them back for the IKH27's since Im going to bump up my power again a tad.

What would be suggested for dual maps of E85 and 93, go with the IKH 24's or do a stock heat range still? Guess Ill be sending my IKH27's back
