What intervals do you guys change your plugs and wires at?

Which ones do you use? I know that BOSCH = The Suck. Which performance adding ones do you guys like?

Just curious.

NGK iridium plugs and real AC Delco wires at 100K miles.

Thats good for stock rides. If your modded then a copper based plug such as the autolite line will be better although you have to change them a bit more often (every 30k or so). Lightly modded cars should look at autolite 605'* or 104'*. (1 and 2 heat range cooler respectively).

Hey Rogue I got 606s autolite should I use 605 next time.

606 is stock heat range I think, 605 is 1 step cooler. I recommend them for anyone with light mods on a supercharged car. On an N/A car your not buliding up extra heat so stock range and gap are fine.

I should have researched more , I thought 606 were cooler than stock and I just put them in a week ago, I only run a 180 thermo and a FWI no real mods.If I change to a smaller pulley guess Ill change plugs again.605
