This 2-pack catalytic converter set is designed as a direct replacement for select Ford and Lincoln vehicles with a 3.5L V6 engine. It features a 400-cell honeycomb structure with a ceramic carrier and 600-molybdenum catalyst to help improve exhaust filtration and flow. The T409 stainless steel construction is built to resist heat and rust for long-term durability. Its bolt-on, flange-to-flange design and included gaskets support easier installation. An integrated M18 O2 sensor port is included for compatibility with original vehicle oxygen sensors.
