When you're chasing maximum output from your pre-12/2013 N55-powered BMW, fueling is everything. The Dorch DS15B High-Pressure Fuel Pump Upgrade is the definitive choice for drivers demanding uncompromised fuel delivery under heavy load.

Dorch engineered this kit to step up where the factory hardware falls short, providing rock-solid pressure stability and increased flow capacity. Tailored precisely for early N55 models, this kit ensures your engine receives a steady, high-volume of fuel, allowing you to maximize your tuning potential on the street or the circuit. Elevate your BMW’s performance limits with proven hardware.
