1 Step Colder Spark Plugs -- EVO IX
Can anyone tell me which spark plugs will fit the EVO IX that are 1 step colder? I have searched and haven't foound anything besides greddy and HKS making them and them costing $100 for a set. Aren't there any NGK's Iridium's or coppers that are 1 step colder that fit the EVO IX?
thanks.
thanks.

Same as stock, but with an 8 instead of a 7... Why do you want colder plugs?

I recently got a m1 flash from jestr, and it was knocking a bit so figure to take care of that i should buy a set and throw them in there to see if it helps a bit. I was considering coppers, any part specific part numbers on these plugs?
Axiom power is charging a bit much last time i requested a price for these plugs so thats a no go...

Although there is limited discussion on IX plugs, the info applies to choosing brand/type of plug and discusses the need for changing heat range...which applies across engine types. It's also to show that choosing plugs should be the product of careful research and consideration of needs/design.
That said...you're welcome, and good luck!
