I hate plat plugs... I'm running a pair of NGK copper that work out to be one step colder then stock. I'll post the P/N when I get home if you're intersted.

NGK DCPR9E They were $3.00 each.

I also had Denso irridiums, I can't find the box now, but you can get the P/N off thier site. I like the copper better, but if you want longer life irridium is the way to go.
