Fuel Injector & Oxygen Sensors

Shop New OEM fuel injectors and oxygen sensors for GM vehicles. Our factory-original injectors and O2 sensors are sourced from GM surplus — the correct flow rate, spray pattern, and sensor calibration for your engine's fuel and emissions management system.

Fuel injector flow rate is precisely matched to your engine's fuel pressure, injector pulse width, and desired air-fuel ratio. An OEM injector provides the factory flow rate without recalibration of the ECM's injector scaling tables. Similarly, OEM oxygen sensors provide the correct output voltage curve for your engine's closed-loop fuel control strategy.

Replace oxygen sensors in pairs (upstream or downstream) for consistent system performance. Verify part numbers against your engine RPO code.
