Hey all,

I am changing my plugs on the weekend, have a stock 1997 SSEi - no mods. The car normally runs hot and I live in Indiana where is does get hot in the summer.

What spark plugs would everyone recommend I put in the car? Should I go with ACDelco, NGK or Champion? Someone here mentioned that the TR55 NGK plugs run cooler, would that be a good choice? Any ideas would help me.

Thanks a bunch,

Andrew

just stick with the delco'*... they're a good plug (and as i noted in an almost identical post by another member about 2 minutes ago in the performance forum), and the iridium ones i picked up two weeks ago, despite their delco packaging and print on the porcelain, the base had NGK stamped into the side of it...

they're a good plug, and you really don't need to worry about colder ranges until you start modding...

I currently run the AC Delco Platinums in my 93 and NGK TR55s in my 99. I would highly recommend either. They are both solid performers. Just stay away from Bosch!!

I have heard it said that platinum plugs should *not* be used in an SSEi ... but I've never tried it myself (since I haven't owned an SSEi), and I don't know the technical reasons for that recommendation. But you really can't go wrong with the bone stock AC Delcos!

don't go for bosch'*! I had to replace them because they would misfore after a 2,000 miles. I put autolite'* in after them and they work great!

No problems with Bosch here (both cars).
Could it be the supercharged engines you guy are having troble with?
Or maybe the +4'*?

I'm willing to try the NGK'* once the Bosch plugs bit the bullet.
Are these the ones at Advance Auto $1.99

You should see my Bosch platinum single electrode plugs after 25k miles. On two of them the platinum center electrode is gone, there is just a hole at the end of the insulator. Strange but true.

thanks everyone, I stuck with the AC Delco Rapidfires. They cost me $4.19 each at Autozone.

The old ones I pulled out had done 41K miles, and were still great.

Platinum anything is bad in any car with boost.

Anyone interested in a Tech-Info writeup.
