Who's running NGK ZFR5N in there Slant?

Hey Charlie.... Champion..... screwing? Huh? That's how plugs go in , they screw round and round.
No matter the brand.

One combo that I have NEVER had luck with is ACs in a mopar. Tried it a few times when they were out of the right champions for what I was driving, every time I wound up with an overpowering whine in the speakers whenever the radio was on.
