Banks Power Ram-Air Cold Air Intake System with Dry Filter for 2017-2019 Chevrolet/GMC 2500/3500 HD (6.6L) 42249-D

Fits 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD models equipped with the 6.6L Duramax L5P engine.

The Banks Power Ram-Air Cold Air Intake System (42249-D) is engineered to replace the restrictive factory air box, delivering a 70% increase in airflow to your Duramax L5P. By utilizing an enclosed housing to isolate the oversized dry filter element from power-robbing engine bay heat, this system ensures a cooler, denser air charge. This improved air-fuel ratio allows the engine to run leaner, which directly reduces soot output and decreases the frequency of DPF regeneration cycles.

• Outflows the stock intake system by 70% for improved throttle response.
• Standalone performance gain of +20 hp; increases to +81 hp when combined with a Derringer inline tuner.
• Enclosed housing prevents heat soak and maintains lower intake air temperatures (IATs).
• Oversized dry air filter element provides superior filtration and extended service life without the need for oiling.
• U.S. Patent #10,138,851 B2.
• Includes all necessary hardware for a direct-fit installation.

• Manufacturer Part Number: 42249-D
