• Description:

  This is a genuine Ford catalytic converter outlet gasket for the 3.0L twin-turbo V6 engine used in 20-26 Explorer, Lincoln Aviator, and Police Interceptor Utility models. Ford specifies the gasket as a single-use part that cannot be reused once removed, and it is offered for both left and right outlet positions. The gasket seals the high-temperature flange joint between the outlet of each catalytic converter and the connecting exhaust pipe. Allowing exhaust to bypass this joint creates an audible leak, distorts upstream and downstream oxygen sensor readings, contributes to lean operation under boost, and triggers diagnostic trouble codes for catalyst efficiency and lean fuel trim. Common reasons buyers need this part include catalytic converter service, downpipe replacement, turbocharger removal on the integrated-manifold 3.0L engine, oxygen sensor work, or a noisy exhaust ticking that worsens with engine load. The OEM Ford gasket uses a multi-layer crush design rated for the temperatures the 3.0L V6 reaches under boosted operation, and it deforms around the flange features to seal once the bolts are torqued. The catalog name is Catalytic Converter Gasket; Ford notes the part cannot be reused. Install a fresh gasket each time the flange is opened, clean both mating faces, and torque the flange fasteners in the specified sequence with new hardware where the service manual requires it.

• Notes: Part cannot be reused/reinstalled.
