S58/B58 BMW Stage 3 LPFP Upgrade Kit for G Chassis BMW

Shooting for big power on your B58 or S58? You need this low fuel pressure pump upgrade! 

Our stage3 low pressure upgrade adds in an additional Walbro pump to fuel up to 900whp with the 450 pump or up to 1100whp with the 525 pump!   

This unique low pressure fuel pump (LPFP) kit is the only one on the market that retains full function of your direct injection fuel filter AND your low fuel pressure regulator! Eliminating the concern for clogging expensive direct injection fuel injectors or worse blowing out the factory plastic lines which so often happens with competitors kits.

This is a full DIY kit that you can install at home in under an hour. The second pump can be triggered off your port injection controller including ReFlex, CANfuel, or JB4PRO, or even off a simple boost activated Hobbs switch!
