Irridium or copper are fine for your car, as are platinums. Just stay away from bosch and stick to either AC Delco or NGK.

Iridiums are a newer "best/better" plug. GM puts them in most of their "100K before a tune up" cars.

Like my 00 truck. I didn't touch them til 100K and the gap was ridiculous, at the least they should be pulled and regapped.

I put them into my cars and was unsure, I thought the 97SC ran warmer w/iridium than Tr55'*.

Cost difference was large between tr55'* and iridiums, all other things seem equal. Sonoma said he felt more power with the 55'*.

I doubt I'll go back to iridiums in my cars.
