Alliant Power AP63544 Intake Air/Charge Air Cooler Temperature (IAT/CACT) Sensor

Ensure Accurate Intake Temperature for Optimal 6.7L Power Stroke Performance

The Alliant Power AP63544 Intake Air/Charge Air Cooler Temperature (IAT/CACT) Sensor is a direct-fit, OE-quality replacement designed for 2011–2017 Ford Super Duty trucks with the 6.7L Power Stroke diesel engine. This critical sensor continuously monitors the temperature of the incoming air, allowing the engine control unit (ECU) to adjust fueling, timing, and boost for maximum power, efficiency, and emissions compliance.

Vital Role in Engine Management

A properly functioning IAT/CACT sensor delivers precise intake air temperature readings, enabling safe turbocharger operation, efficient combustion, and optimal response in all driving conditions. A failed or inaccurate sensor can cause poor turbo performance, excessive smoke, check engine lights, reduced power, or failed emissions tests.

Key Benefits:

• Restores accurate intake air temperature data for the engine computer

• Supports proper turbocharger, EGR, and emissions system operation

• Prevents power loss, rough running, and excessive emissions

OE-Quality, Rugged Construction

Engineered to meet or exceed original equipment specifications, the AP63544 sensor provides reliable, stable data—even when exposed to high heat and vibration common in heavy-duty diesel use.

Design Features:
