Spool Performance is proud to introduce our upgraded DI injectors for the Toyota Supra Gen2 B58 Platform. The IFX 350X is the highest flowing Gen2 B58 injector on the market and is carefully sized for the B58 Gen2 engine to keep stock-like idle and low load characteristics while allowing 60% more injector flow at high load and high rpm conditions. 

Flow: 60% over stock DI injectors 

Pressure: Capable of flowing at up to 390 bar pressure

Tune changes are required for running these injectors. Spool Performance will provide full calibration support for the same on all existing tuning platforms for the Gen2 B58
