Air Intake Heater for RAM 4500 5500 (2008-2018) 6.7L

Direct-Replacement Air Intake Grid Heater for 2008-2018 RAM 4500, 5500 (DP Chassis)

What it Does: The Air Intake Heater restores critical intake charge pre-heating on the 2008-2018 RAM 4500 and 5500 to help ensure dependable cold starts and eliminate excessive unburnt white smoke in freezing operating environments.

The Stock RAM 4500, 5500 Grid Heater Degradation

Commercial-duty cycling takes a severe toll on the factory intake manifold heating element. Constant thermal shock cycles break down internal resistance ribbons, causing open circuits, high electrical resistance, or terminal post oxidation. On high-hour Cummins ISB 6.7L commercial trucks, severe carbon fouling and degraded electrical connections impede current draw, triggering extended cranking, hard-start diagnostic trouble codes (DTCs), and incomplete combustion that foul downstream emissions systems.

The Engineering Solution

Manufactured to restore precise amp-draw specifications without modification, this replacement grid heater assembly drops directly into the intake tract beneath the horn. Built with a high-conductivity, heavy-gauge heating element housed in a rigid stamped-metal casing, it features side-by-side terminal studs to interface seamlessly with OEM power leads. Included with the assembly are two high-temperature composite flange gaskets to help ensure an airtight seal under high-boost conditions, preventing boost leaks and unmetered charge-air loss.
