Standard Motor Products AIP53 Secondary Air Injection Pump

The Standard Motor Products AIP53 is a direct-fit OE-replacement Secondary Air Injection Pump, also commonly known as a smog pump or air pump. Engineered to restore proper function to a vehicle's emission control system, this all-new (not remanufactured) unit is built to meet or exceed original equipment specifications for reliable, long-term performance.

The secondary air injection pump plays a critical role in reducing cold-start emissions by injecting fresh air directly into the exhaust stream, which accelerates catalytic converter warm-up and lowers harmful exhaust output. A failing pump can trigger a check engine light, cause rough engine performance, slow acceleration, or result in a failed emissions test.

Key Features:

• Direct-fit OE replacement — ensures proper fit, form, and function for straightforward installation
• All-new construction — contains no remanufactured components for improved reliability and longevity
• Steel-alloy housing — withstands extreme operating temperatures for superior durability
• High-grade rubber mounting bushings — resist vibration and shock for greater load-bearing capacity and abrasion resistance
• OE-matching connectors and terminals — ensure an exact-fit connection to the engine wire harness
• Designed to prevent backflow of exhaust gases into the secondary air blower or environment
• Manufactured and tested to meet stringent quality standards

The Standard Motor Products AIP53 is part of Standard's extensive Air Pump program, covering a wide range of import and domestic vehicles. Trust Standard Motor Products for a dependable, emissions-compliant repair backed by decades of automotive expertise.
