I think the rev limit is set to 6700 though, at least that's what I was told. Pretty sure that's what my tach read when I hit the limiter in my 93 XE awhile back. Maybe you were being sarcastic, but $62 is cheap compared to what a lot of so called "premium" plug sets go for. Funny thing about plug wires, people spend $100+ on Nology's and what not, but unless you're running an MSD high voltage ignition, the expensive wires won't help you any. Then you've got guys that put an MSD ignition in and don't upgrade their coil and distributor, so they waste the potential of that as well.
