what are the best spark plugs for a 1997 firebird 3.8 v6
life and performance

 

might want to try f-body.com

This site is for 82-92 camaros.

 

YOu need a 4th gen site. This is a 3rd gen.

And if thats is a Buick 3.8 you would be best off in a Buick GN,GNX,T type site that is all about just the 3.8

Not much can touch a twin turbo 3.8

 

I'm not an authority on fourth Gen cars by any means, but I've had people with them come into the parts store I work at asking for Bosch platinum +4's. Might want to ask around about them before you try them though, they're $5.99 each. Supposed to be wonderful spark plugs, but like Dale said above I'd ask other 4th Gen owners what they think about them compared to OEM plugs.

Autolites aren't too bad for GM's in most applications (Although I've heard Autolite makes Motocraft), AC Delco's are OEM and are usually recommended, and regular Bosch platinums are pretty good as far as I've seen. Just make sure you stay away from Champions, they suck for anything that isn't made by the Chrysler Corp.

Platinums are supposed to have longer life.

 

Another 4th gen (93-up) f-body website with a V6 board is http://www.camaroz28.com .
