What Is Secondary Air Injection?

The Secondary Air Injection system is an important emissions control feature that injects fresh air into the exhaust manifold during cold engine starts. This fresh air helps burn off unburned fuel in the exhaust gases, accelerating the warming of the catalytic converter and reducing harmful emissions. By promoting cleaner exhaust, the system helps your vehicle comply with environmental regulations and improves air quality.

Vehicles equipped with the SAI system require this specialized wiring harness to ensure all components communicate effectively and the system functions properly.
