The 20R1266 injector cat provides precise, high-pressure fuel atomisation into the combustion chamber of the CAT engine, ensuring complete combustion, full power output, and minimal emissions. A failing injector delivers incorrect fuel quantities and spray patterns, causing rough running, power deficiency, increased fuel burn, and the risk of carbon build-up in the combustion chamber. Built to OEM specification 20R1266 for direct fitment on the CAT, restoring complete combustion efficiency from installation.

Key Features:

  • High-Pressure Injection Accuracy: Provides accurate fuel delivery timing and volume for full power and efficient combustion.
  • Direct OEM Replacement: Built to specification 20R1266 for exact fitment on the CAT.
  • Combustion Restoration: Eliminates rough running, power loss, and excessive smoke caused by a worn or clogged injector.

The 20R1266 injector cat is an essential fuel injection component for maintaining power output and fuel economy on the CAT.

What Does This Injector / Fuel Pump Assembly Do?

Delivers a precisely metered, high-pressure fuel spray directly into the combustion chamber at the timing commanded by the ECU. Correct injector operation is critical for power output, fuel efficiency, and meeting emissions requirements.
