3C3Z-9C623-AA air intake duct for Ford 6.0L diesel

Air intake duct for the 3C3Z-9C623-AA application

This aftermarket inlet duct is supplied as one black moulded hose with two metal band clamps, one at each end. It is listed against reference 3C3Z-9C623-AA for Ford 6.0L diesel applications. The curved body has a round side connection and two raised mounting bosses with threaded inserts.

Check the 6.0L diesel application by VIN

For F-250, F-350, F-450 and F-550 Super Duty, confirm that the vehicle's parts listing calls for 3C3Z-9C623-AA. Ford's current catalogue lists this reference for 2005 trucks with the 6.0L diesel engine. Other years need individual confirmation against the VIN, build date and existing intake arrangement.

Compare both end connections, the bend, the side-port position and the mounting-boss spacing with the removed duct. A truck model name or engine size alone does not establish a match, particularly where the intake has been changed.

Prepare the adjoining connections

The duct carries filtered air toward the engine. Before fitting it, inspect the adjoining intake ends, side connection and retained hardware. Seat the hose ends fully, reconnect the side port as specified for the vehicle and follow the service instructions for clamp positioning and tightening. Check that the curved body clears surrounding parts without forcing the connections into place.

The supply shown is the duct and its two clamps. Sensors, an air filter, an air-cleaner housing and loose mounting bolts are not included.
