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, without software tuning the coil output is xxxMj with software tuning available from most major software and tuning companies the coil output can be increased to 118mJ. To put this in perspective the factory coils have an output of only XXmJ so this kit increases output XXX%! All components used meet or exceed OEM requirements and feature seals which are both dust and water resistant. So buy the most robust and highest output coil and stop replacing coils constantly, stop fighting misfires, & enjoy better throttle response, smoother idle, and even more power out of your N55 today! OEM Manifold Kit - Mounts to the DI fuel rail. May require removal of the factory airbox, and removal of post on manifold (Cars that have airbox on top of the intake manifold) Aftermarket Manifold - Intended for use with a Black Market Parts aftermarket intake manifold and mounts to the mounting tabs for the Port Injection fuel rail. *Aftermarket intake highly recommended and may be required on some applications. Not compatible with OEM airbox (or any airbox that sits on the manifold in the same location as the coils) and may require removal of a mounting peg on the manifold. **F10 and e9x N55 Chassis cannot fit both ignition kit and aftermarket manifold due to inlet location across the back of the engine.
