Hella 7.03635.38.0 Secondary Air Injection Pump

The Hella 7.03635.38.0 Secondary Air Injection Pump is a precision-engineered emissions control component designed to reduce harmful exhaust emissions during engine cold starts. This electric air pump actively introduces fresh air into the exhaust stream during the critical warm-up phase, promoting secondary combustion of unburned hydrocarbons and carbon monoxide before they reach the catalytic converter.

Key Features:

• OE-quality construction meeting stringent emissions standards
• Electric motor-driven design for active air injection
• Accelerates catalytic converter warm-up for optimal efficiency
• Engineered to withstand harsh under-hood temperatures and conditions
• Integrated check valve protection prevents hot exhaust backflow
• Precise airflow delivery for proper secondary combustion reaction

Secondary air injection systems are critical for meeting modern emissions requirements, particularly during the first 60-100 seconds of engine operation when fuel mixtures run rich. A failing secondary air pump can trigger check engine lights, cause increased emissions, and result in failed emissions testing. Hella's reputation as a leading OE supplier ensures this replacement pump delivers reliable performance and proper fitment.
