Are you NA or FI?

I would not regap iridium or platinum plugs. You may run into issues with the plugs firing early, but timing will likely adjust

So iridium wears slower vs platinum and sparks easier vs platinum?? I guess I'm buying the iridium then.

I replaced my factory plugs (plats) at 50k miles , the center electrode was worn down and that caused the gaps to be over the service limit. The replacement plugs I installed were the Iridium version of the factory plugs (exact same plug except with iridium center electrode), the center electrode won't wear down as quickly so the gaps will remain more stable over the long term, they've been working fine for two years now.

This is what I gathered from my thread.


Copper - best but wears faster
Iridium - better
Platinum - ok


Im interested in the copper since its so cheap and I dont mind paying 9-10 dollars every 20k if it will maximize performance/fuel efficiency.
Anybody with a part number from Advance/Napa because Autozone does not have them in stock and I plan on doing tune up this saturday.

$2/plug every 20k miles or $10/plug every 100k miles. I'll take the latter.
