Faster starting, smoother running, more power! You will be amazed at the improvement this kit will make in your vehicle. Your rig will start faster, run smoother, and have more power and better fuel economy too. This ignition kit consists of Performance Distributors' LIVE WIRE plug wires, Screamin' Demon coil, brass terminal cap and rotor. The Screamin' Demon coil allows you to run an astounding .065 sparkplug gap, which gives you a much more powerful burn of your fuel mixture yielding increased horsepower and fuel economy.
Worked great for a 1997 XJ, noticed some throttle response when I increase gap to 60.

4.0Cap and wires great, wrong plug.
Took awhile to get the parts in as they were on back order. Cap and wires work great so far. The ignition coil has the wrong plug-in on the back so I could not instal it. Moderately bummed about that. Will be contacting 4wheelparts to get the correct one.
Quicker start up, and more responsive throttle.
