This Harness replaces only the signal and power sub harness portion of the Motiv Reflex.

Rid your BMW's N55 of misfires, sluggish throttle response, rough idle, and power loss with Precision Raceworks' High-Performance Ignition Kit! Precision Raceworks' ignition kit is designed to fit any vehicle with an N55 engine and offers the highest output of any kit on the market! Featuring 100% Plug-&-Play connections, low resistance 50ohm/ft proprietary plug wires, and design technology from Marine and Aerospace applications, these coils are guaranteed to output consistent high voltage and current for optimal ignition system performance and reliability. Every component in this kit meets or exceeds OEM quality and features premium seals for dust and water resistance. While coils do not directly increase horsepower, stock BMW coils can wear out quickly, resulting in underperforming voltage and current output. This often leads to weaker spark intensity and reduced power outpaut. Due to the increased voltage and current output, many customers have seen as much as 20+ whp/wtq gained by switching to Precision Raceworks coils over all other coils on the market! By upgrading to Precision's Performance Ignition Kit, spark quality can be restored, and lost power regained often with the additional power beyond what other coils provide. No software tune is required for installation or operation, but if desired, coil output can be increased to 118mJ from most software tuning companies! Features: Fits any N55 BMW engine w/ the stock intake manifold 100% Plug & Play! Highest Voltage and Current Output Available Low Resistance 50ohm/ft proprietary plug wires Eliminates Ignition Related Misfires Improves Throttle Response Restores Smooth Idle Specifications: Weight: 9lbs 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 FITMENT NOTES: OEM Manifold Kits mount to the DI fuel rail. May require removal of the factory airbox and removal of the post on the manifold (Cars that have airbox on top of the intake manifold). 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.
