K&N Aircharger Intake System - 2017-2019 Chevy Silverado & GMC Sierra 2500/3500 (6.6L Duramax) - 63-3101

The K&N 63-3101 Air Intake fits some Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500 HD, GMC Sierra 2500 HD, and GMC Sierra 3500 HD models. See vehicle applications link for details. The K&N AirCharger 63-3101 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-3101 air intake comes with a K&N high-flow air filter and a high density polyethylene air box and lid. This allows cooler, denser air to be directed through a custom molded air intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.
