Our 5.2/5.9 ignition upgrade kit includes parts that you will need to replace on your donor. These are some of the best and highest performance pieces available in one convent package. The upgrade includes MSD 8.8mm Spark plug wire set, MSD Blaster Coil, NGK V-Power Spark Plugs and a Standard Blue Streak Cap and Rotor. The wire set is custom tailored for the Dodge Magnum engine, the coil is Mopar specific and the Cap and Rotor have solid brass terminals to prevent spark scatter with the larger plug gap we use. An upgrade that you can really feel in the old seat of the pants dyno!
