Precision Raceworks Auxiliary Injector Feed Line for BMW N54 and N55 Plate Manifolds

Unlock dependable fuelling on tuned BMW straight six builds with this direct fit auxiliary injector feed hose from Precision Raceworks. Designed for plate style PI manifolds, it integrates with the factory high pressure pump and main chassis feed using OE style quick disconnects, then finishes at the plate rail with an AN6 ORB outlet. Ideal for ethanol blends and flex fuel calibrations, this line delivers stable supply under boost on M135i, 135i, 335i, 435i, 535i, 640i, 740i, Z4 35i and more. Also works with many S55 plate based PI kits.

Connections are CNC machined from 6061 aluminium and anodised for corrosion resistance and full E85 compatibility. The smooth bore PTFE hose resists permeation and retains fuel chemistry, while dual sealed female quick connectors provide a tight, leak resistant fit. Installation is straightforward with no cutting or splicing, keeping the bay tidy and serviceable.
