Install our new High Voltage Screamin’ Demon Coil on your Wrangler 3.8 Liter V6 and open up the spark plug gaps to a massive .065″! The larger plug gap exposes more spark to the fuel mixture for the most complete combustion possible. A more complete burn means more horsepower and better fuel economy! Quicker starts and a smoother idle are additional benefits gained from the Screamin’ Demon Coil. The Screamin’ Demon features brass terminals for maximum conductivity and the unit is epoxy filled for improved heat transfer and vibration resistance. Installation is easy as this coil mounts in the original factory location.
Delivering a high voltage spark to the plug requires a quality spark plug wire. Our LiveWires are unsurpassed in quality by offering low resistance and high temperature protection. The 8 mm wire is covered by a heat treated fiberglass sleeve that protects the wire up to 1400° F. The spiral wound core is radio suppression so there is no radio noise or computer interference. Unlike universal plug wire sets, LiveWires do not require any assembly. All sets are custom fit and numbered at each end for the correct cylinder. Available in red, black, blue, purple, silver and yellow, the LiveWires give your 3.8 the best plug wire technology along with a high performance look.
