      Better Engine Performance. Unlock your Sierra 2500 HD’s true power by installing the K&N Series 77 High-Performance Cold Air Intake. Crafted with a mandrel-bent intake tube, this system is capable of introducing higher amounts of air into your engine. Moreover, it utilizes a superior quality air filter that prevents harmful particles from damaging your engine, giving you a cooler and more consistent airflow. This results in higher torque and horsepower, as well as improved fuel efficiency.

      Hassle-Free Air Filter. Aside from providing you with excellent performance gains, this High Flow Performance Cold Air Intake is also designed for easy maintenance. The included air filter is a washable and reusable oiled cotton High-Flow Air Filter™ media that only needs to be cleaned after reaching 100,000 miles. Take note that this only applies under normal highway driving conditions. If exposed to rugged off-road trails, it might need to be cleaned earlier.

      Can Handle Heavy-Duty Drives. The 77 High Flow Performance Cold Air Intake is your best option when looking for a cold air intake system that can keep up with your heavy-duty drives. Featuring an aluminum intake pipe and stainless steel clamps, you can rest assured that this unit will stay intact no matter how fast you’re going. Plus, it comes with a durable heat shield to protect the cold air intake components from the heat emanating from your truck’s engine.

      Simple Installation. You won’t have any difficulty installing this high-quality cold air intake. It’s designed to replace your factory unit, so it mounts on your vehicle’s OE locations. It also doesn’t need to be drilled or cut to ensure a perfect fit. All the procedure requires is the use of basic hand tools and 3 hours of your time.

      Covered by a 1,000,000-Mile/10-Year Warranty. K&N offers a 1,000,000 miles/10-year warranty against defects in materials and workmanship for every 77 High Flow Performance Cold Air Intake sold. Some exclusions may apply, so please refer to the manufacturer’s website or contact customer support for more details.

      Application. The K&N Series 77 High Flow Performance Cold Air Intake fits all 2017-2019 6.0L Sierra 2500 HD models.
