i was going to do a spark plug change tomarrow on my stock 97z28 was wondering if anyone has used these plugs
Premium Class Iridium plug 5325 IT16 .060" $11.99
i really dont want to do it again for awhile 12$ a plug is kinda crazy but if that last and perfome good i'll be happy

Also i was looking at the pass side and was thinking taking off the altanator and maybe the starter and y pipe-- looks like it would be a hell of alot easer i have big hands

also the 02 sensor's
Super Class OE identical O2 sensor 234-4012 234-4012 FRONT; 2 Sensors Required for Vehicle; $36.75

Super Class OE identical O2 sensor 234-4087 234-4087 REAR; $55.69

I think the Iridium stuff is overrated. Just go with copper. Works just as good and much cheaper.

i was thinking of going with those densos for my lt1. a friend of mine runs densos in his ls1 and he said he noticed a difference when he changed the plugs,for what thats worth...

I use TR 55 IX (the iridium flavor 6.99); don't have any proof they are better but it does feel like my car idles smoother.

heh I just saw the ad banner up top for those plugs you want.

I really don't think they work any better than normal plugs, it's just the last longer. You might get a cleaner spark out of them, but that'd be about it I'd think. The cost is just too much for me to ever want to. Delco and NGK for me.
