BMW R90 CP3 Fuel Pump Upgrade for all EXX M Engines is the go-to high pressure fuel pump upgrade for E-series BMW diesel performance builds. This R90 CP3 HPFP is a direct replacement for the factory R70 pump and delivers substantially more fuel with stronger, more stable rail pressure. Perfect for tuned and remapped M47N, M47N2 and M57N2 engines, this upgrade supports higher power reliably and helps prevent pressure drop at high RPM.
We have used this upgrade ourselves on multiple builds and our customers have been delighted with the improved rail stability, faster response and added headroom for performance tuning. If you are chasing reliable fueling on your BMW E-series diesel, this is the fuel pump you want.
