Hi have any of you guys used Denso IK22 spark plugs for your car? My buddy has a extra set and im wondering if i should use them. Thanks

 

Irridium plugs arent good in the Evo, I don't rember which your supposed to use but its around here somewhere.

 

3SGTE, please stop saying that iridium plugs aren't good. They are very good for the Evo - that's why they come stock.

Evoryne, I do not recommend using Denso plugs. If you want Iridium replcements, then use NGK BPR7EIX. If you just want to use some basic copper plugs, then get NGK BPR7ES, which cost less than $2 each.

 

Warr, quick question. Do you gap the NGK BPR7EIX the same as the NGK BPR7ES ?

 

I use the NGK BPR7EIX and love them, and quit giving me those dam misfire CEL
You dont gap iridium plugs, you'll break the tip
