You could be right on that the problem was with the 7173's being non resister plugs but I'll just stick with the 2668 iridium's also. The car ran great with them when I had them and they do last a long time.

 

Yep, much better plug all the way around, worth the money.

 

 

Those plugs actually look good to me. One thing though, make sure to put antiseize on the threads so you dont get a plug stuck in the head.

 

yeah, those plugs do look pretty good to me as well.


I normally use high temp grease instead of antiseize, most people use entirely too much and antisieze sticks to everything, grease will burn off if it gets in the motor
