Evo 8 plugs do not fit the Evo 9.

I just called Buschur Racing and the told me to run NGK BR8ES.
EVO IX SE with the 20G-LT and meth kit.

That's an Evo 8 plug. See post above yours.

aer you sure? are the BR8's the same as the BR7's?

They are too short and thick. They don't work very good in my 9 so i put the factory ones back on.

ngk all the way

i thought the ix's used sti plugs.

get the part number from the dealer.

the ix's do use the same plugs as they sti's i just ordered the 1 step colder plugs from denso .

stick with the stock plugs on the ix. they are colder then the viii plugs

have a quick question... I had a buddy over the other night, and we were talking about plugs, and I asked him if he had any experience w/ different plugs... Im running the stock ilfr7h's (for IX's), and they came in a silver box... He replied w/ "those are the wrong ones"... He says that they should be in a white box... Now Im not sure if he's right or not. This is my second set, and they both were in a silver box.. They had the correct part # on the box...

if you get them straight from mitsu they are in white mitsu boxes

I've been using the Denso 1-step colder plugs for the majority of my 75,000 miles on my Evo with no issues at all.

They can be had in the neighborhood of 55 bucks/set. I order from Chris at Nolimit. Don't waste your money.

I picked up the denso ikh24 from optionsauto.com for around 40$ or 45$ shipped
