Quick question opinion.... 2001 XJ 4.0L - changing the plugs ... any real need to also change the coil pak? Starts okay, runs okay, no misfires, no skips, fuel mpg okay...

But, not terribly expensive to change out.. worth doing anyway??

Swab some Dielectric Grease in there with a Q-tip too.

Nah. It's pretty amazing how long these coil rails last.
