The K&N 63-3113 is a complete cold air intake system designed for 2019-2021 Chevrolet Silverado 1500 and GMC Sierra 1500 models equipped with the 2.7L L3T turbocharged inline-4 engine. This enclosed system replaces the restrictive factory airbox to deliver dyno-tested gains of +18.47 HP and +18.78 TQ at 3100 RPM while protecting intake air from engine bay heat. Pairing a roto-molded HDPE tube with a high-flow oiled cotton filter ensures more power and cleaner operation across the RPM range.
Key Features
- High-Flow Oiled Cotton Filter: Oversized conical shape captures dirt while flowing more air, cleans every 100,000 miles under highway driving with simple wash-and-reoil service.
- Roto-Molded HDPE Tube: Increases airflow volume to the turbocharger with smooth mandrel-bent design for measurable horsepower and torque improvements.
- Product weight 7.7 lbs, ships in box 22.8 x 14.5 x 9.8 inches.
- Bolt-on design completes in 60 minutes or less with common hand tools like pliers and screwdriver.
- Filter service interval up to 100,000 miles under normal highway conditions with K&N cleaning kit.
- Every intake dyno-tested for real-world power gains and emissions-compliant design.
