Chevrolet Silverado 3500 Performance Air Intake by K&N — 63 AirCharger (2020–2027). A bolt-on intake and air box kit engineered to improve airflow and throttle response for your 6.6L Duramax.

An enclosed air box shields inlet air from engine heat, and a tool-free lid speeds filter access. The HDPE roto-molded tube increases airflow volume, paired with K&N’s oversized oiled-cotton High-Flow filter that’s washable and reusable—allowing up to 100,000 miles between services under normal highway driving. Typical installation takes under an hour with basic tools. K&N guarantees an increase in horsepower and torque and backs the system with a No-Hassle Lifetime Limited Warranty. Will not void vehicle warranty.
