The Precision Raceworks BMW N54 HIGH PERFORMANCE IGNITION KIT is designed to integrate with any vehicle equipped with the N54 engine. This is the highest output ignition system ever developed for the N54 community Featuring 100% plug and play connections and low resistance 50ohm/ft proprietary plug wires. High voltage & High Current coil design using 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.
