ACDelco 215-345 GM OE Secondary Air Injection Pump

The ACDelco 215-345 is a GM Original Equipment Secondary Air Injection Pump — a direct OEM replacement designed to restore proper emissions system function. Also referred to as a smog pump or A.I.R. pump, this component is a critical part of your vehicle's emission control system.

The secondary air injection pump forces fresh air into the exhaust stream to support combustion of unburned gases, reducing harmful emissions and helping your catalytic converter operate at peak efficiency. A failed pump commonly triggers a Check Engine light and emissions test failure.

• GM Original Equipment part — designed, engineered, tested, and backed by General Motors

When replacing a worn or failed secondary air injection pump, trust ACDelco GM Original Equipment to deliver the same fit, function, and reliability as the part originally installed at the factory.
