Spool Performance FX350 S58 upgraded high pressure fuel pumps

Spool Performance is proud to introduce our latest and greatest high pressure fuel pump capable of delivering fuel at 350 bar/ 35Mpa/ 5000psi for S58 platform. The pumps features a stainless-steel construction with high tolerance DLC coated piston and bore. The pump is engineered to deliver the same volume as our FX200 pumps but at 350 bar pressure.  The plunger springs have been specially engineered to be compatible with the S58 dual pump design and the high revving engine. They are fully E85 compatible and would let you run Full E85 on your S58 powered vehicle.

The FX350 coupled with our IFX350 Gen2 DI injectors is the long-awaited missing piece in the puzzle for DI only big power on the Gen2 BMW high pressure fuel system.

The FX350 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 FX350 pump.
