INDUSTRY-LEADING ENGINE PROTECTION FOR CHEVY AND GMC

THE WORLD’S BEST AIR FILTER™

The included intake tube is engineered to flow a high volume of air, and an oiled High-Flow Air Filter™ (also included in the kit) helps increase airflow to your engine—while simultaneously providing exceptional protection from contaminants. The oversized filter shape allows for up to 100,000 miles between cleanings (under normal highway driving conditions). When it does need to be cleaned, you can use a K&N Recharger® Kit to quickly and easily restore your filter’s performance. Each intake and filter is designed to last for the life of your vehicle.

The installation of the Intake Kit was very simple and completed in less than an hour and a half. The performance of my 2015 GMC Sierra is so much better now than it was with the stock air intake and my gas mileage has improved. Purchasing this Performance Intake Kit was worth every penny.” – Robert from Georgia [Part No. 63-3082]

CAD-DESIGNED INTAKE TUBE INCREASES AIRFLOW

Since engine combustion is most efficient in an oxygen-rich environment, keeping engine air cooler often significantly increases engine combustion efficiency. The 63-3117 system features a roto-molded HDPE intake tube designed to keep airflow to the throttle body smooth and oxygen-dense.

FEWER BAFFLES IMPROVES ENGINE SOUND

Factory intake systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and muffle engine noise—unlike K&N® intake systems, which are designed to give your engine a more satisfying growl on acceleration, but return to quiet once at speed.

Easy to install. Love the new growl it has now (not over the top but just right). The acceleration & shifting is much improved and I've noticed a little gain in the MPGs in the first 2 tanks.– Bob from Illinois [Part No. 63-3082]

INDUSTRY-LEADING WARRANTY

Each intake system comes with a 10-Year/Million Mile Limited Warranty. Furthermore, using a K&N replacement air intake system will not void your factory warranty; in the U.S., manufacturers must provide evidence that an aftermarket part is the cause of a necessary repair in order to void or deny warranty coverage. The Consumer Products Warranty Act of 1975 (also known as the Magnuson-Moss Warranty Act) protects consumers’ rights to their warranty coverage.

“Fast shipping. Good product. Great price. Easy installation. Better gas mileage on the first tank. Would refer to a friend.” – Bob from Ohio [Part No. 63-1561]

Legal in 49 states. Not legal for sale or use in California on any pollution controlled motor vehicle.

 

*K&N intake systems can typically be installed in less than 60 minutes.


**Horsepower gains vary among products and applications, but each K&N performance air intake system is designed to increase airflow efficiency for specific vehicles and their engines. Each kit undergoes significant testing to help ensure that the filter and intake tube are engineered to deliver large increases in airflow and horsepower.
