Pulled them out of my 4.6 2v Kenne Bell Mustang this morning. I had a mild misfire after taking the car on a road trip to Ohio last October. The new NGK plugs seemed to fix the issue. Anyways, how do the old ones look?


I cant remember how many miles are on them, but I'd have to say no more than 15k.

Look all good as far as combustion goes but that little rust band could have been moisture in the boot causing a misfire??

I had a coolant leak lead to a misfire. Or corrosion in the coil/spring/plug that you broke loose and got rid of the misfire that way.
