Ignition Coil and spark plugs
How often should the ignition coil be replaced. My WJ has 220,000 miles and I have never done it since i purchased it with 85,000 miles on it.
Also, i would like to replace the spark plugs soon. I dont want anything fancy nor dirt cheap but some decent plugs. Any suggestions as to what brand/model?
