N55 Ignition Kit

The Precision Raceworks Ignition Kit is engineered to be the highest output ignition system for the BMW N55 engine community. It boasts 100% plug-and-play wiring with OEM weatherproof quick connectors and proprietary low-resistance 50ohm/ft plug wires. The high voltage and high current coil design draws from marine and aerospace applications, retaining the factory cooled controlled system and offering full DME control. While ignition coils do not directly increase horsepower, the factory coils on N55 engines are often underperforming. This kit has consistently shown gains of 20+ whp and 20+ wtq on tested vehicles, whether stock or heavily modified, as evidenced by before-and-after dyno testing. No software tuning is required for the coil to operate, but with available tuning software, the coil output can be increased from its base level to a maximum of 118mJ. All components meet or exceed OEM requirements and feature dust and water-resistant seals. Installation considerations vary based on the intake manifold. The OEM Manifold Kit mounts to the DI fuel rail and may necessitate the removal of the factory airbox or a post on the manifold. For vehicles with the airbox positioned on top of the intake manifold, these modifications are often required. The Aftermarket Manifold version is intended for use with specific aftermarket intake manifolds and mounts to the port injection fuel rail's mounting tabs. An aftermarket intake manifold is highly recommended and may be required for some applications. It is not compatible with the OEM airbox or any airbox that occupies the same space on the manifold, and may require removal of a manifold mounting peg. Furthermore, F10 and e9x N55 chassis vehicles cannot accommodate both the ignition kit and an aftermarket manifold simultaneously due to the inlet location.
