Keep cold-start emissions control working with the Standard Ignition Secondary Air Injection Pump AIP34. It installs as a direct-fit replacement for the 2006-2011 Ford Focus and the 2006-2009 Ford Fusion, restoring the air-injection function these engines rely on during warm-up.
A secondary air injection pump forces fresh air into the exhaust stream shortly after a cold start. That added oxygen helps the catalytic converter reach operating temperature sooner so the emissions system can do its job during the warm-up period.
Signs the pump may need replacing include a stored air-injection-related trouble code or a check engine light after cold starts. Because those symptoms can have other causes, diagnose the system before ordering. If a failed air pump is confirmed as the cause, this unit replaces it.
Manufacturer part number: AIP34.
