Spool Performance is proud to introduce our flag-ship 350 bar high-pressure fuel pump capable of delivering fuel at 350 bar/ 35Mpa/ 5000psi. The FX400X improves on our existing industry leading FX350 by about 20% across the entire delivery range.
The FX400X coupled with our IFX350 Gen2 DI injectors is a true revolution and the key to DI only high horsepower numbers on the Gen2 BMW high-pressure fuel system.
The FX400X is truly Plug and Play for all platforms we are offering and comes with all the lines and hardware needed for a clean easy install.
As usual, we stand behind our high quality offerings and this product is eligible for our lifetime warranty program.
Tuning changes are required to run the fuel pump and we’re in the process of adding these to the different flashing platforms. Meanwhile our team can assist with adding the required changes to tune files.

Note: Proper low pressure fueling is critical to proper normal functioning of the HPFP.

Please make sure you are running an upgraded low pressure fuel pump to ensure adequate pressure delivery to the FX400X pump.
