• Description:

  This is a genuine Ford downstream exhaust gasket cataloged by Ford as a Converter and Pipe Gasket for 20-24 Explorer 2.3L EcoBoost applications. Ford service procedures and the 2021 Expedition workshop reference both list this part as the single-use sealing gasket between the catalytic converter outlet and the connecting exhaust pipe. The gasket is a flange seal that cannot be reused once disturbed; the material crushes and conforms to the flange profile under torque, which means a removed gasket no longer seals reliably. Symptoms of a failed downstream gasket include a tick or hiss that pulses with engine cycles and increases under throttle, a sulfur or rotten-egg smell at idle, lit check engine light with downstream oxygen sensor or catalyst efficiency codes, exhaust soot at the flange edge, and audible leak buzz from under the vehicle at low speed. Buyers typically need this gasket during catalytic converter service, downpipe replacement, turbocharger work, or any service that opens the flange joint. The catalog name is Converter and Pipe Gasket and Ford lists it as part-cannot-be-reused. Install a fresh gasket whenever the flange is opened, clean both mating faces of carbon and old material, and torque the flange fasteners evenly in the factory specified sequence.

• Notes: Part cannot be reused/reinstalled.
