Spool Performance A90 / A91 Toyota Supra B58 Gen2 FX-350 Upgraded High Pressure Pump

Spool Performance introduces the FX-350, the latest high-pressure fuel pump for the A90/A91 Toyota Supra B58 Gen2 platform, capable of delivering fuel at an impressive 350 bar (5000 psi). This pump is designed with stainless steel construction and a high-tolerance DLC-coated piston and bore, ensuring durability and efficiency. The FX-350 matches the flow volume of the FX200 pumps but operates at significantly higher pressure, making it the perfect solution for achieving big power on the Gen2 BMW high-pressure fuel system.

The FX-350 is truly plug-and-play, offering easy installation with all the necessary lines and hardware included. Coupled with Spool Performance’s IFX150 Gen2 DI injectors, it completes the high-pressure fueling setup for DI-only big power builds.
