Product Description

The Banks Power 42249 Ram-Air Intake System is engineered specifically for 2017-2019 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks equipped with the 6.6L L5P Duramax diesel engine. This high-performance cold-air intake replaces the restrictive factory air system with an enclosed design and oversized high-flow filter to deliver cooler, denser air to the engine. The result is up to approximately +20 horsepower over stock and improved throttle response under load.

Designed to keep hot engine bay air out of the intake path, the 42249 helps lower exhaust gas temperatures and may reduce the frequency of regeneration events on diesel particulate filters. With a 5-year limited warranty and direct bolt-on installation using included hardware, this intake system is ideal for towing, daily driving, and performance diesel applications. Fitment is confirmed through 2019; 2025 coverage is unconfirmed due to the part's age.
