The Hella 7.02256.37.0 is a Secondary Air Injection (SAI) Control Valve engineered to OEM-level specifications. The secondary air injection system introduces fresh air into the exhaust stream during cold starts, helping the catalytic converter reach operating temperature faster and significantly reducing harmful hydrocarbon and carbon monoxide emissions during that critical warm-up period.

Hella is a globally recognized Tier 1 automotive supplier, manufacturing components to the same exacting standards found in original equipment applications. This control valve is designed as a direct-fit replacement, ensuring proper system function and emissions compliance.

Key Features:

• OEM-quality construction for reliable, long-lasting performance
• Precision-engineered to control airflow within the secondary air injection system
• Supports proper catalytic converter warm-up and emissions reduction
• Direct replacement design for straightforward installation
• Manufactured by Hella, a trusted global OEM supplier

Replacing a faulty secondary air injection control valve can resolve issues such as a check engine light (P0410, P0411, or related SAI fault codes), failed emissions tests, and rough cold-start behavior. The Hella 7.02256.37.0 restores correct system operation and helps maintain emissions system integrity.
