I'm getting ready to buy some new OEM spark plugs but don't know which ones to buy...Denso Irridiums or NKG? I think the ones I have in my stock 98 GS3 are Platinums, which are only rated for 60k miles. Which is the replacement I can get that's rated for 90k miles? And would any of you know what the part # is?

Thanks a bunch.

BTW, I know about the Torque Master plug group buy, but I think I'd like to stick with OEM for now.

Alright...I think I found the right part...it's the Denso Iridium plug #IK16. But this is only a single ground electrode, where as the owners manually specifically states to only use twin ground electrode spark plugs. Can I still use the Denso Iridium plug? Any ideas??

i would go to toyota and buy the plugs there, same exact plug for much cheaper...

Denso all the way!! Try looking at www.lexpartsonline.com

That's where I got all my parts to do a tune-up on my previous car (sc400).
