Product Details
About this part
Spool Performance is proud to introduce our upgraded DI injectors for the Toyota Supra Gen2 B48/B46 Platform. The IFX 350X is the highest flowing Gen2 B48/B46 injector on the market and is carefully sized for the B48/B46 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 B48/B46
The injectors are covered by our warranty for a period of 1 year from the date of purchase.
