Just curious if the coil pack on a 2000 XJ should be changed. I just changed the plugs, the XJ has 82k on it, and it runs good, no misfires after changing plugs.

 

No reason to change it unless it's causing problems, they can last the life of the vehicle.
The aftermarket coils aren't up to OEM quality IMHO. I sure wouldn't remove a functioning OEM coil pack to put an aftermarket unit on.

 

edit to remove double post.

 

that's what i was thinking. don't fix it if it's not broke. thanks

 

It's an expensive part just to change for no reason.
