Hey guys, I ran across a ad for these new Denso Platinum TT spark plugs. I know the stock plugs that came out of my STS were Denso so I was wondering if you guys would recommend these. Im almost tempted to try them out and see how they perform.

The ACDelco Professional Platinum plugs are made in Japan. Probably by Denso, as they were the OEM supplier for spark plugs, alternators, and who-knows-what-else in the mid-late year Seville line.

The Denso numbers have changed to ACDelco 41-950 for pre-2000, and 41-987 from 2000 to 2004. $5+ apiece at RockAuto.
