    • Works with OEM computer system
    • Includes the world's best air filter, the K&N filter
    • Easy to install

    There are two problems with your OEM air induction system that cause restriction and reduce airflow. First, airflow is restricted by the size of the filter in the factory airbox. Even a replacement performance air filter can only flow so much when its size is limited. Second, the air path from the filter to the throttle body can be restricted by the OEM intake tube. Together, these two areas of restriction combine to reduce airflow and rob horsepower from your engine.

    Luckily, these problems are easily solved with a K&N 63 Series Aircharger Intake Kit. K&N starts by replacing the restrictive airbox and small air filter with the largest size conical shaped high flow K&N air filter that will fit in the engine compartment. The great increase in filter area over stock vastly improves airflow and the capacity to capture and hold dirt. Then K&N replaces the OEM intake tube with a precision designed, rotationally molded tube made from interlaced high density Polyethylene. This tube eliminates air path restrictions to the engine and reduces air intake temperature when compared to similar metal tubes. Intake air temperature is further reduced by a heat shield that isolates the filter from the engine compartment. The reduction in air intake temperatures results in a cooler, denser air intake charge and even more horsepower. All components are mounted and connected with high quality materials such as steel, aluminum, silicon or reinforced nylon, to ensure long life.

    K&N uses a dynamometer to design its air intake kits to make the most horsepower possible. But their power figures aren't based on just one vehicle, but rather an average of runs by a number of vehicles. This means repeatable numbers and horsepower claims you can count on.

    Every 63 Series Aircharger Intake Kit comes complete with everything necessary for installation, including comprehensive installation instructions. The K&N filter can go up to 100,000 miles before cleaning is required. And the K&N air filter is guaranteed for one million miles.

    K&N® is the inventor and leading innovator of reusable cotton gauze filter technology for automotive applications. The first K&N filter was conceived for racing over 40 years ago and a performance enthusiast mindset continues today throughout all levels of the company. K&N is the sales and brand leader for performance filters, including an extensive line of factory replacement filters and performance air intake kits. The company actively promotes the environmental, economical and performance advantages of long-life reusable cotton gauze filters.

    Warranty Information

    Find out everything you need to know about the product warranty

    K & N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.

    K&N Aftermarket Air Filters should be cleaned every 50,000 miles for normal highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not specifically designed to clean and re-oil cotton air filters (i.e. gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.

    Any K&N product returned to K&N will need a Return Goods Authorization number and must be sent at customers' expense along with proof of purchase.

    Any defective K&N Air Filter properly returned to K&N will be replaced. K&N reserves the right to determine whether the terms of the warranty, set out above, have been properly complied with. In the event that the terms are not complied with, K&N shall be under no obligation to honor this warranty. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages.

    We want to make sure that when you buy a K&N Lifetime Air Filter or Air Intake System, you can be confident your vehicle's warranty will not be impacted. We also want you to feel confident that even if you experience difficulties with a dealership repair department, we will step-in and resolve the issue, so you won't have to. Therefore, K & N makes the following Pledge: K&N pledges to their customers that they will not be taken advantage of and charged for a repair due to a manufacturer warranty denial blamed on the presence of a K&N product.

    Magnuson-Moss Warranty Act:
    Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More

    Great Product, Great Service.
    The intake looks great; even better than I expected. My 2013 Silverado is noticeably quicker now. Installation was a little complicated because the description of the tools needed was not specific enough. Still, I'm very pleased with the end result.

    Installed the unit last weekend. The installation instructions could have been better. The bag of parts was not clearly labeled. Once that was straightened out, it was a simple installation. The product has made a difference in performance and sound.
