Catalytic Converter for Ford F-150 (2009-2010) 5.4L Left & Right

Direct-Fit Catalytic Converter Set for 2009-2010 Ford F-150 (P415)

What it Does: The catalytic converter set replaces deteriorated factory catalytic assemblies on the 2009-2010 Ford F-150 to restore proper exhaust gas velocity, clear P0420 and P0430 diagnostic trouble codes, and re-establish standard emissions conversion.

The Stock Ford F-150 Catalyst Substrate Breakdown

Over extended mileage, factory converters on the P415 platform suffer from internal washcoat thermal sintering and carbon fouling. Fuel trim irregularities and ignition misfires inherent to aging 5.4L 3V Triton engines melt down or degrade the factory ceramic honeycomb matrix. This failure restricts exhaust flow, spikes thermal backpressure against the cylinder heads, and triggers persistent downstream efficiency codes (P0420 and P0430).

The Engineering Solution

Engineered to direct-fit original equipment standards, these replacement units feature heavy-gauge stainless steel outer shells that resist corrosion and road heat cycle fatigue. Inside, a high-efficiency ceramic core saturated with precious-metal catalyst material expedites light-off times to chemically reduce HC, CO, and NOx emissions. Precision-formed tubing with 2-bolt loose female flare flanges guarantees leak-free sealing with factory downpipe joints and intermediate pipes, while integrated pre- and post-catalyst sensor bungs ensure plug-and-play installation of your oxygen sensors without modification.

Frequently Asked Questions & Fitment Warnings

Does this fit the P415 F-150?

Yes, this is a direct fit for the 2009-2010 Ford F-150 equipped with the 5.4L 3V Triton engine. Not compatible with 4.6L V8 or 6.2L V8 models, and not legal for sale or use in California, Colorado, New York, or Maine.

Do I need to replace oxygen sensors during installation?

Replacing both upstream and downstream oxygen sensors is strongly recommended to verify proper air-fuel trimming and prevent premature damage to the new catalytic substrates.

The Ford Towing Standard

Constructed to manage elevated exhaust temperatures under heavy payload and towing scenarios, this system keeps your F-150 running clean and unchoked through the hardest working conditions.
