I am planning on changing my spark plugs tomorrow on my day off and wonder what would be the best ones to get for my car? I have seen a few people on here post about some Iridium kind of plugs, are they good? I also am putting a Fenderwell Intake on and a 3.5" pulley just for a little more power. Should I just stick with copper ones, and if so, which ones should I get? Thanks, Brad

Use NGK TR-55'*.
They're one heat range cooler. Good way to combat the extra heat that you're gonna be putting into the motor by droping pulley sizes. Also too look into a cooler thermostat.

Cool thanks for the help. By the way, I also am putting in a 180* Thermostat tomorrow too. I called Autozone today too, and they said they do not have the NGK TR55'* in stock. They don't carry them. Anywhere else I can pick them up at? Thanks again, Brad
I believe that NAPA carries them. Also, IIRC AutoZone does carry them, but under a different number. There was a discussion about this a while back I believe. I'll see if I can find something, no promises...lol.

Also if Advance is close to you they should carry them..

Ok, now I put the new 104'* in and all new spark plug wires in, but the car seems to be running a little rough! The car is not throwing any codes, and it seems fine when I give it a little gas, it only is rough when I am idling!! What could be wrong? Any ideas? Please help ASAP!! lol Thanks, Brad
EDIT: I just noticed on the slip from ZZPerformance that sent the plugs to me, that the gaps are set to .055 from them. Shouldn't they be .060? Thanks again, Brad
