Product Description

While the factory fuel system is adequate for stock vehicles these engine quickly run out of fuel with even basic performance upgrades.

Our extensive work with Xtreme-DI has revealed this pump can expand the tuning and performance opportunity of your N55 motor. This is a complete bolt on upgraded and comes with everything needed to make installation easy. 

The installing of the pump is fairly easy but, it must be accompanied by custom base tuning to work correctly which, is also included and you can use our tuning services for performance tuning or have your preferred tuner (i.e. BM3, MHD, TTFS) take your N55 to the next level with this brilliant upgrade!
