Useful Information

Description and Purpose:

This Genuine Cab Heater Intake Filter by Mack comes new with Part number: 3543-H9638 and is designed to protect the HVAC intake path in heavy-duty truck cabs. Its 10” length, 9-7/8” height, and 1” width allow the filter to capture dust, debris, and fine contaminants before they enter the heater system, ensuring clean, stable airflow for interior ventilation and operator comfort. Cross reference: 3543H9638

Why Replacement is Important:

A clogged or deteriorated intake filter reduces the volume of air entering the HVAC system, which can lead to weak cabin heating, restricted ventilation, and increased strain on the blower motor.

Impact on Vehicle Performance:

Maintaining a clean intake filter helps keep cabin airflow consistent, supports effective temperature control, and prevents unnecessary load on the HVAC system, improving comfort and overall operating efficiency for the driver.

Manufacturer Information:

Mack® delivers dependable heavy-duty components built to maintain consistent performance and withstand demanding fleet operation.
