Be prepared for 10 different answers ;) Some like champion, some like autolites, ngk's, e-3's, or ac delcos just to name a few
 
everyone has there own plug they like

for me right now i like

ngk UR5's gapped at .032
 
nothing wrong with AC Delco either. prior to the NGK's i ran

AC CR42TS gapped at .032

as for the .032 gap that im running. i have a good ign. system so i can gap them at .032 and run 28psi. if you start upping boost and get spark blow out just gap them to .030 and try again. if your system is really weak .028 i would go past that,
 
Our cars do NOT like platnium!

I am unable to get information about iridium.

Currently I'm using copper plugs.

AS earlier mentioned, there are many opinions as to brand. I have found some brands to have poor quality control, when examining 6, some will be standard gapped & some will be J gapped - i don't use those brands.

I think you are correct. I replaced the AC's in my car cause I didn't know how many miles were on them.
Well car runs like **** under boost with the AP24's.:redface:
AC plugs actually looked real good. Prolly gonna stick 'em back in:smile:.
 
Ouch....Seem like a lot have had good success with those....Did you just change the plugs after that and the problem went away?

Yes. I've read that fancy plugs like these and split fire plugs are no good for our cars. Who has had good luck with them?
