Detailed Description

This AP Exhaust catalytic converter is engineered for select 2009-2010 Ford F-150 left-side applications, including the 4.6L VIN 8 24-valve 4WD configuration and Federal/California emissions setups listed in the fitment data. Part number 645247 is built to OE dimensions for proper alignment with the factory exhaust layout, helping maintain the original routing and connection points on the vehicle.

AP Emissions Technologies uses proprietary substrate chemistry and advanced manufacturing methods to produce converters with efficient loading and consistent fitment. For buyers searching for a 2009 Ford F-150 catalytic converter left side or a 2010 Ford F-150 direct-fit catalytic converter, 645247 provides a vehicle-specific replacement option.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Failed or restricted catalytic converter performance
• Check engine light concerns related to catalyst efficiency
• Exhaust flow issues caused by a damaged converter
• Emissions compliance problems on the listed Ford F-150 applications
• Fitment problems from non-direct replacement parts

Installation Notes and Tips

Verify the vehicle’s engine, emissions configuration, and left-side application before installation. Confirm the inlet and outlet connection style, O2 sensor port count, and overall length against the original converter to ensure proper fit on the Ford F-150. Because this part is listed for Federal and California emissions configurations, check local regulations before use.

Quality Assurance

AP Exhaust builds this converter to exact OE dimensions using automated workstations, spinner welding equipment, and high-speed production lines to support consistent fitment and manufacturing control.
