Precision Raceworks BMW N54 N

Auxiliary Port Fueling Kit for BMW N54 and N55 - Precision Raceworks with 6 Bosch 750 cc Injectors and -6AN Rail

Push your turbocharged straight-six further with a proven secondary injection solution. This Precision Raceworks PI manifold with integrated -6 AN fuel rail and six genuine Bosch 750 cc/min injectors gives tuned N54 and N55 engines the headroom required for high ethanol blends, bigger turbos and serious boost. Expect stable fuelling, smooth drivability and consistent cylinder-to-cylinder distribution on builds that are outpacing the limits of the factory high pressure system.

We use this hardware on our own workshop cars and customer builds and it has been faultless - clean idle, crisp throttle response and strong top end on E85 and flex fuel calibrations. It is a favourite among UK enthusiasts running hybrid twins, single turbo conversions and track-focused setups who need reliable additional fuel delivery.
