Includes: Nostrum FA20F High Pressure Fuel Pump and Nostrum FA20F Stage 1 DI Injectors

The more power you make the more fuel you demand, that’s why Nostrum High Performance offers top of the line high pressure fuel pumps with a larger diameter piston to increase fuel capacity. Our rebuilt OEM cores feature corrosion resistant internals that are dynamically tested and flex fuel compatible.

Nostrum upgraded DI injectors increases fuel flow 10% while retaining an OEM equivalent spray pattern. Stage 1's are perfect to bump that build! These injectors are compatible with the Stock ECU and require zero additional accessories or connectors (tuning with COBB Recommended). Easy to install, simple to tune; this price friendly stage 1 DI injector upgrade is available to ship now! (While supplies last!) The perfect injector upgrade for those Stock ECU 375 to 525 whp builds!
