Alliant Power AP54905 Remanufactured Fuel Injector for 2017+ Silverado / Sierra HD Duramax L5P

Remanufactured Alliant Power common rail fuel injector, part number AP54905, for the Duramax L5P (2017+). Each unit ships from our Florida warehouse, checked against the OE part number before it leaves.

Signs your injectors need attention

• Hard starting or long crank time
• Rough idle, misfire or a knock that was not there before
• White or black smoke, loss of power or worse fuel economy
• Injector balance-rate or contribution codes on the scan tool

Before you install

• Find the root cause first. Contaminated fuel or a failing pump will damage new injectors.
• Replace sealing washers, O-rings and any one-time-use hardware.
• Common rail injectors carry a trim code (IQA / IMA). Program it with a scan tool after installation.
