The Spool Stage 3 LPFP kit delivers almost double the flow of the stock pump and features a twin pump solution with the secondary pump activating at boost onset for seamless delivery under load. Ideal for 550i, 650i, 750i, M850i, X5 50i and X6 50i owners chasing safe, consistent power on both petrol and E85.
We have used this Spool Performance BMW N63 Stage 3 LPFP on our own builds and customer cars, and feedback has been excellent for drivability, reliability and fueling headroom. If you are pushing the N63 platform, this is the low pressure fuel system upgrade you want.
Why upgrade your BMW N63 LPFP
With modern direct injection systems, once high pressure pumps are upgraded, the OEM in-tank low pressure fuel pump often becomes the bottleneck to power, especially on ethanol blends. The Spool Performance Stage 3 LPFP solves this by delivering significantly increased low side fuel volume to supply the HPFPs properly at high load and high boost, maintaining pressure and keeping your N63 happy on petrol or E85.
