Help protect the engine of your Silverado or Sierra and gain a guaranteed increase in horsepower and torque with the K&N® 63-3109 air intake system, engineered specifically for 2019 Chevrolet Silverado and GMC Sierra 1500/2500 5.3L/6.2L V8 models. The K&N® 63-3109 roto-molded air box intake system boasts an estimated power increase of 15.7-horsepower and 32.5 lb./ft. of torque*, and up to 25% more airflow than the factory intake system.
CAD-designed in order to help ensure a precise fit, the 63-3109 is engineered to effectively utilize space in the engine bay and reduce airflow restriction. An 8-inch conical filter with 600 square-inches of filter media helps ensure exceptional airflow and contaminant capture, and a 17 square-inch opening is precisely placed to utilize the vehicle’s stock source of cool air.
An enclosed air box design helps protect the filter and inlet air from the heat of the engine bay. The air box lid attaches with a pin-and-grommet style mounting system, allowing for quick and easy access to the filter without tools.
WHY A K&N PERFORMANCE AIR INTAKE SYSTEM? BOOST HORSEPOWER AND TORQUE!
The 63-3109 is designed to help keep engine air cooler, which can increase engine combustion efficiency, and helps provide a smooth, low-restriction path for airflow to the engine. Your engine needs oxygen to create power; the cylinders in your vehicle’s engine have to have air to create the explosion that produces horsepower and torque. Since cold air contains more oxygen molecules than warm air, injecting a higher volume of oxygen-rich air into the cylinders allows the engine to burn fuel more efficiently during combustion—providing an increase in power.
In a typical stock air intake system, air has to pass through a thick, disposable paper filter, and then move through a narrow system of tubing that can cause air to swirl and become turbulent. Excess turbulence causes the molecules within the air to collide, creating heat, which lowers the density of the air and reduces the efficiency of combustion. All K&N intake systems are specifically engineered to help keep your engine air cooler.
“I was happy to find out how easy the install was. Sounds great when you jump on the throttle. Thanks for all your great service.” – Tom from California [Part No. 69-4523TP]
AERODYNAMIC 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 63-3109 intake system features a free-flowing, high-density polyethylene intake tube, which is engineered to reduce turbulence in the air, which helps keep engine air cooler and increases engine performance! The 63-3109 also incorporates an enclosed air box design, which helps protect the air filter and intake air from high temperatures within the engine bay.
“Very easy to install—takes about an hour. Definitely noticed a power improvement when towing my trailer. Well worth the money.” – Paul from Pennsylvania [Part No. 63-6014]
HIGH-FLOW AIR FILTER™ OFFERS EXCEPTIONAL PROTECTION
Under normal circumstances, most automotive air filters demonstrate an inverse relationship between airflow and efficiency—the higher the airflow, the less efficient the air filter is at protecting the engine, and vice versa. The oiled design of K&N air filters assists in “absorbing” dirt particles—and in turn helps incorporate those particles into the filter surface itself, which helps maintain the filter’s efficiency and ability to flow air. When tiny particles are captured and saturated with oil, they in turn can become tacky, allowing them to capture other particles.
The High-Flow Air Filter™ included in the 63-3109 intake kit is oversized with a conical shape, providing a greater surface area and allowing for a service interval of up to 100,000 miles between cleanings (under normal highway driving conditions). High-Flow Air Filters feature an oiled, layered design—providing up to 50% more airflow than a traditional paper filter. When your filter does need to be cleaned, you can use the K&N Recharger® Kit (99-5000 or 99-5050) to quickly and easily restore your filter’s performance. Each K&N intake (and filter!) is designed to last for the life of your vehicle.
“Great buy. Before I got it, I was skeptical about it. It makes the truck a little faster and definitely improves the sound when you get into the throttle. Would definitely recommend this product to anyone.” – Derek from Michigan [Part No. 77-3082KP]
The K&N 63-3109 intake system is engineered to incorporate factory mounting points and the factory mass air sensor. Installation can typically be completed in 90 minutes or less, and requires only simple hand tools. Detailed instructions are included in your kit, and installation videos for many vehicles are available on the K&N website.

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.
“Couldn’t be happier with this intake. Easy installation, great sound and noticeable performance. Looks great, sounds great and performs as advertised. Well done K&N.” – Shawn from Raleigh, NC [Part No. 69-8621TTK]
K&N performance air intake systems come with a horsepower guarantee—you will get an increase in horsepower and torque! During dynamometer testing, the 63-3109 provided a power increase of approximately 15.7-horsepower and 32.5 lb./ft. of torque*. View the full dynamometer chart here.
*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.
