Description:
This Genuine GM Fuel Injector (12644527) is an OEM DENSO Common Rail injector used on the 2.5 L Duramax diesel engine in Holden Colorado, Chevrolet Colorado, and select Trailblazer models.
Take-off units are removed from brand-new engines and have never been run in service, offering near-new performance at a lower cost than new OEM units.
Ideal for restoring factory fuel delivery, efficiency, and smooth operation on your 2.5 L Duramax diesel engine.

Why Choose Genuine GM:
Genuine GM fuel injectors are built to factory specifications for precise fitment, proper spray pattern, and long-term durability. Avoid aftermarket injectors that may fail prematurely or cause engine performance issues.
