spark plug help with pictures
I know my 93 yj is close to 21 years old and the original 2.5 runs fine for its age but if it can run better why not. The following pucs are of spark plugs with approximately 2k miles on them. They are in order from the radiator to the tub ( front to back). Do they look normal...any issues? Thanks.
