What is Secondary Air Injection?

The Secondary Air Injection (SAI) system reduces emissions by pumping fresh air into the exhaust stream during cold starts, helping to burn off unburned hydrocarbons. If your vehicle is equipped with this emissions system, you will need a compatible harness like this one to maintain proper engine and emissions performance.
