The Precision Raceworks BMW N55 HIGH PERFORMANCE IGNITION KIT is designed to integrate with any vehicle equipped with the N55 engine.  This is the highest output ignition system ever developed for the N55 community Featuring 100% plug and play connections and low resistance 50ohm/ft proprietary plug wires.  This High voltage & High Current coil design is equipped with technology from Marine & Aerospace applications. While coils do not increase horsepower unless the coil they are replacing are not doing their job the factory coils are lacking in proper output so much that all cars tested (stock or heavily modified) gain 20+ whp and 20+ wtq!  Before and after dyno testing can be seen here. Software tuning of vehicle is NOT required. With software tuning available from most major software and tuning companies the coil output can be increased to 118mJ.   Features: Gain 20WHP & 20WTQ over factory Coils Full DME control of ignition coils: Yes Retains factory cooled controlled system: Yes 100% Plug and Play wiring: Yes Connection style: OEM Weatherproof Quick Connect Coil output: Up to 118mJ Available in Black & Blue Features Precision Raceworks Logo What's Included: Precision Raceworks Ignition Kit
