Default Spark Plugs?

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.

The NGKs are considered to be one of the best for our cars, either copper or iridium for heat transfer to run cooler. Also try Belden wires from NAPA.

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.

OK, back...here'* some tidbits from this thread: Spark Plugs

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

Do not put irridium plug if you go smaller pulley. just NGK TR-55 or TR6.

edit: I meant platinum, not irridium...

Default HELP!

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
