APR 7th Injector System Upgrade for 1GR TRD Supercharger System

Click to enlarge

• Increased fuel delivery for higher boost
• Reduces Compressor Discharge Temperatures
• Improves impeller to housing sealing for more boost
• Required for 2.7" high boost pulley upgrade

This additional injector upgrade system will spray additional fuel into the supercharger inlet and provides additional fuel and cools the compressed air leaving the supercharger.

As the performance of TRD's Supercharger system for the 1GR-FE engine is pushed out with higher boost you may want the additional fuel to prevent lean out and to cool the increased compressor discharge temperatures.

It can also be used with the basic TRD Supercharger system for cooling of the compressed air.

This is intended to be used with the APR X-1 Advanced Engine Management System and new X-1 calibration files are available.

The APR 7th Injector System includes:

• Fuel rail adapter
• Stainless braided fuel line
• Throttle body spacer injector mount with injector fuel rail
• 630cc mini injector - high impedance
• Injector harness
• All needed hardware and gaskets
• X-1 calibration file
