K&N Series 63 AirCharger Cold Air Intake (14-18 4.3L Sierra 1500)
Up Your Acceleration. The K&N Series 63 Aircharger Cold Air Intake replaces the entire factory air intake system so that your engine can be cooled consistently and efficiently. The lower temperature afforded by this system gives your engine additional horsepower and acceleration speed. This way, you can count on your vehicle's quick response while on the road.
 
Cold Air, More Power. How is it possible that your engine receives cool air all the time? Unlike your stock air intake system, the K&N Series 63 Aircharger Cold Air Intake has an oversized air filter and high-density polyethylene tube. This setup lets in a high volume of air and keeps it away from the engine's hot compartment.

Made to Last. Thanks to its high-performing air filter, durable components, and high-quality parts, the K&N Series 63 Aircharger Cold Air Intake's lifespan is unbeatable. It'll take the system 100,000 miles before it needs to be serviced.

Application. The K&N Series 63 Aircharger Cold Air Intake was specifically designed as a bolt-on performance upgrade for any 2014-2018 4.3L GMC Sierra model.
