Alright so I got an 89 XJ with a 95 Engine and i wanna give it the good ol'tune up. Now i was thinking of getting a better ignition system, any recommendations for that one? Spark plugs, o2 sensor, CPS, plugs & wires. Any ideas of what i can do to make my cooling system better? And i also want to get a little more performance out of it, i was thinking of a t-body spacer aswell.
