Man for a plug as expensive as thay are you'd think they'd last as long as they're supposd to. I pulled them yestarday after less than a year of use and the pucks were gone off two plugs. Guess I'll just stick with the NGK plugs from now on and save some bucks.

Been there, done that... 40 bucks waisted, too....

 

mine lasted less than 30k miles and i was getting hesitation on acceleration.

 

ngk = pressed plug = trash

buy some autolite 103s

 

A/C Delco plugs are GREAT...on a stock engine. They fouled easily in my '94Z. I used NGK's and never had a fouling problem since. No probs!
