WOW! You are stepping on the toes of your own hipocracy now, glc!

What is wrong with giving members part numbers? I guess, this means, that you are above your own comments huh? Tippie toe around me friend!

 

At least I said exactly where to look them up, arsehole. I also posted the exact numbers in his real thread.

 

tell you the truth any iridium plug that will fit in the motor with the same heat range should dooooo just fine....

I run the denso iridium's

 

Denso's are fine as long as you use the correct heat range. That's what Troyer sells as part of their ignition upgrade kit.

 

i have a 1997 f150 and they put champion plugs in the truck and it runs like crap. i put autolite plugs in and runs 100% better run autolites or motorcraft

 

Your one of the lucky ones then- My truck ran for 40 miles on Autolites. Then it started running on 6 cylinders. Had to to Install Motorcrafs to fix. Autolites don't work well / wrong heat range and NOT Ford spec.

The 97,98 5.4L COP'ed motors are picky as hell when it comes to plugs.
