hello smart monster people,
i was going to change my plugs the other day, but then i wondered if there are better plugs than champion. my manual says to use ra59gc (champion says that that plug does not exist, but the comprable heat rating would use a59c). what plug do you board members use and what is the true comprable plug to the campion ra59gc. thanks for the helpl!

don't know the NGK # for an S4, but go NGK.
uhmmm.... looked at the NGK website. they don't show an application for the s4!!

i think the S4 has a "normal" 916 or 996 head, thus it can get the "D" family of plugs... any of these will work:
- D8EVX platinum
- DCPR8EVX platinum (oops, those are all gone now...)
- DCPR9EVX platinum
- DP8EVX-9 platinum (oops, those are all gone now...)

you can exchange the "VX" for "A" to go from platinum to "standard"

i currently have some Nippon Denso plugs for testing. I got a couple of "u groove" platinum as well as one of their iridium plugs. i consider ND's iridium plug to be better than the NGK iriduims, which are all resistor and have the "EIX" suffix.

I have a 2001 S4, which Nippon Denso plugs should I get? How much should I expect to pay for them? I was quoted 16 a piece by a dealer.
