Hella Secondary Air Injection Pump

The Hella Secondary Air Injection Pump (also called an air pump, smog pump or secondary air pump) is part of the emissions control system. During cold start, it forces fresh air into the exhaust stream. The extra oxygen helps burn off unburned hydrocarbons and carbon monoxide. It also helps the catalytic converter reach operating temperature sooner.

Key Features:

• Electric pump design that supports the vehicle's secondary air injection system
• Helps reduce cold-start emissions and supports emissions compliance
• Built to OE-style quality standards, as expected from Hella, a long-time supplier of automotive electrical and electronic components
• Made for dependable operation and durability under demanding underhood conditions
• Replaces a worn or failed pump to help clear related check engine lights and fault codes

A failing secondary air pump can cause a check engine light, emissions test failures, or a noisy or inoperative pump. Replacing it with a quality Hella unit restores proper emissions system function. Select the correct part number for your application from the options listed on this page.
