Used Secondary Air Pump And Smog 1990–2019

We carry 14 used secondary air pumps from 10 makes. The secondary air pump, or smog pump, pushes fresh air into the exhaust stream during cold starts. This extra oxygen helps the catalytic converter reach operating temperature faster and burn off unburned fuel in the exhaust, reducing cold-start emissions. When the pump fails, you get a check engine light for the secondary air system and your vehicle may not pass emissions testing. The pump motor burns out, the check valve sticks, or the relay fails. These are emission-critical components, so the codes won't clear until the system is repaired. Our 4 sellers stock Secondary Air Pump And Smog assemblies for Chevrolet, Honda, Infiniti, Mercedes Benz, Ford and other vehicles. New pumps from the dealer are expensive. A used one that's been tested and spins freely is a cheaper alternative. Browse Redline's secondary air pump inventory and get your emissions system sorted.
