Hella 7.22295.66.0 Secondary Air Injection Shut-Off Valve

The Hella 7.22295.66.0 is a secondary air injection shut-off valve designed to control the flow of fresh air into the exhaust system during cold starts. This valve is a critical component of the secondary air injection system, which helps reduce emissions by introducing oxygen into the exhaust stream to promote complete combustion of unburned hydrocarbons.

Key Features:

• Precision-engineered valve assembly for reliable air flow control
• Manufactured to OE specifications for proper fit and function
• Durable construction designed to withstand exhaust system temperatures
• Direct replacement for worn or failed original equipment
• Helps maintain proper emissions control system operation

When the secondary air injection shut-off valve fails, it can trigger check engine lights, cause rough idle during warm-up, and potentially lead to emissions test failures. This Hella replacement valve restores proper secondary air system function, ensuring your vehicle meets emissions standards while maintaining optimal engine performance during cold starts.
