Walker Air Charge Temperature Sensor 20-22 GM 6.6L Duramax L5P BOR-BNRTC-TDHD-2BL 875-inch diameter for superior corrosion

875-inch diameter for superior corrosion resistance

but also increases cooling efficiency due to its all-aluminum bar and plate style construction

or high horsepower builds

The patented design forces air up and into massive heat radiation fins providing the fastest cooling on the market and creates high velocity air to overcome the "dead air zone" behind the differential cover

this oil pressure gauge is ideal for engine protection and performance monitoring

Walker Air Charge Temperature Sensor 20-22 GM 6.6L Duramax L5P BOR-BNRTC-TDHD-2BL 875-inch diameter for superior corrosionIs your Duramax running rough, losing power, or showing poor fuel economy? The Walker Air Charge Temperature (ACT) Sensor is designed to restore the accurate intake air data your engine needs to perform at its best. This sensor measures the temperature and density of the air entering your engine and sends that information to the ECM, allowing it to fine tune fuel delivery and timing. When it fails, your truck can exhibit hesitation, a rough idle,
