High-Performance Airflow. This K&N Series 77 High Flow Performance Cold Air Intake System is a free-flowing aluminum tube air induction kit designed to replace your entire factory intake system. It reduces airflow restriction by smoothing and strengthening the flow of air, allowing your engine to take in a larger amount of air than your old factory installation did.

Guaranteed Horsepower. A better airflow means more power and acceleration for your 2014-2018 Sierra. This system from K&N directs air through the intake tubing and into your engine's throttle body. The result is a guaranteed and noticeable gain in power.

Great Mileage. The intake tube is built to last, featuring aluminum construction with a chrome-like finish. In addition, the cone-shaped, oversized air filter lasts up to 100,000 miles in standard driving conditions before you'll need to service it. The filter is washable and reusable, making it even easier to get the most out of your performance air intake kit.

CARB Certified. Best of all, this Cold Air Intake is 50 state legal for the 2014 model year under CARB EO Number D-269-49. Unfortunately, the Cold Air Intake is not carb certified for the 2015-2018 model year

Application. This K&N Series 77 High Flow Performance Cold Air Intake is easy to install in about an hour and is designed to fit your 2014 to 2018 5.3L or 6.2L GMC Sierra.
