Dorch Engineering BMW N55 35i Fuel Pump HPFP Stage 2

£1,775.00 Inc Vat

This is a complete plug-and-play kit to support up to 550whp (this number can vary quite a bit depending on tuning strategy and the blend of ethanol). There’s no cutting, no bending, no crimping, etc. This kit drops right in with full control from the DME, just like the OEM pump. All of the safety and sophistication of the stock DME remain in place.
