Product Details

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.

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.
