Why choose this pump?
-
Reliability & Safety (CRITICAL): This pump comes from a newer production batch and features the updated “anti-rotation pins” (pinned bucket) technology. This factory improvement prevents the pump plunger/bucket from rotating within the bore. This design drastically reduces the risk of the notorious CP4 “self-destruction” failure (metal shavings in the fuel system), making it one of the safest CP4 options on the market.
-
Tuning / Upgrade Potential: This is the highest-flow diesel pump originally fitted to the M50d (quad-turbo) models.
-
Bolt-on Upgrade: An excellent upgrade for standard BMW N57 and B57 engines.
-
Performance: With this pump, appropriate turbo upgrades, and tuning, you can reliably achieve 550+ HP and massive torque without suffering from Rail Pressure drops.
