Overview — HEATER, INTAKE AIR 3328445
3328445 is the intake air heater used on CUMMINS engines to warm the intake air for reliable cold starting and cleaner combustion. We can supply this heater as well as the related family numbers listed below, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The heater is built to the original element rating and mounting pattern, with the heating coil, body and electrical connection matched to the CUMMINS intake manifold. The element reaches working temperature quickly and the housing seals against the manifold bore. Wiring and terminal orientation follow the original layout so the harness connects without modification. As an OEM-spec heater, it restores the original cold-start performance.

Maintenance & Replacement
Inspect the intake air heater when cold-start problems appear, looking for a burnt element, damaged insulation and corroded terminals. Test the element resistance and the relay and wiring circuit before condemning the heater. When replacing, clean the manifold bore, fit the heater with a new seal, and torque it to specification.
