Detailed Product Description

The Dorman 306-016 Secondary Air Injection Pump is engineered to support the emission control system by injecting fresh air into the exhaust stream during cold starts.

The plastic housing offers resistance to corrosion and heat, contributing to the pump's durability under typical operating conditions.
