Hella Secondary Air Injection Control Valve

The Hella Secondary Air Injection Control Valve, also called a secondary air injection (SAI) combination valve or air pump check valve, helps manage the secondary air system on your engine. During cold starts, the system pushes fresh air into the exhaust stream. This helps the catalytic converter reach operating temperature sooner and lowers hydrocarbon and carbon monoxide emissions.

Key Features:

• Controls secondary air flow: opens and closes to direct air from the secondary air pump to the exhaust system when needed
• Emissions support: helps the vehicle's emissions system work as designed
• Backflow protection: helps keep hot exhaust gases from flowing back toward the air pump and related components
• Hella quality: Hella is an established original equipment supplier to automakers, and its replacement parts are built to match OE form, fit and function
• Direct replacement: designed to replace a worn or failed valve without modification

A failing secondary air injection valve can cause a check engine light, secondary air system fault codes, rough running on cold starts, or a failed emissions test. Replacing it restores proper secondary air system operation. Choose the specific part number for your application from the options listed on this page.
