Performance Distributors DUI-45350 S.O.S. Ignition Coil Set for 05-08 Jeep Grand Cherokee WK, Commander XK & 02-07 Liberty KJ with 3.7L Engine

Performance Distributors newest addition to the S.O.S.-Sultans Of Spark Coil lineup is now available for the Jeep 3.7L and 4.7L engines. Their new S.O.S. Coils are designed with updated technology and enhanced windings. This has allowed them to increase voltage for each coil from 25,000 to 35,000 volts under load. That's 10,000 more volts per coil for a total of 80,000 volts over the stock Jeep ignition system! The extra voltage under load, also known as the acceleration phase, increases spark intensity for a more complete burn of the fuel mixture. Plug gaps can be opened to .055? and this improves throttle response, horsepower and fuel mileage. Additional benefits include quicker starting and smoother idle. Brass terminals provide corrosion resistance and improved conduction. SOS Coils mount in the OEM location with no modifications.
