Warm the intake charge before it reaches the cylinders with the Standard Ignition Engine Air Intake Heater DIH13. This intake air heater drops in as a direct-fit replacement for the 1999-2003 Ford E-350 Super Duty, 1999-2003 Ford F-250 Super Duty, 1999-2003 Ford F-350 Super Duty, 1999-2003 Ford F-450 Super Duty, and 1999-2003 Ford F-550 Super Duty, all with the V8-7.3L engine. It heats the air entering the intake so the engine has a warmer charge to work with during cold-weather starting.
If a weak or failed intake air heater is the cause of hard cold starts, a rough cold idle, or excess startup smoke, this unit replaces it. Consult the vehicle service information for the correct installation and torque procedure.
Manufacturer part number DIH13.
