EXPLORE THE BENEFITS

COLD AIR INTAKES 101


K&N® cold air intakes are designed to create a more aerodynamic path for airflow by removing stock intake tubing that can create excess turbulence, and by utilizing highly airflow-efficient filter media. Air first passes through a performance air filter—which is designed to provide more airflow than a standard disposable paper filter—before moving through an aerodynamically-engineered tubing system that helps keep airflow cooler and also helps provide a higher volume of air to the engine.

INCREASE HORSEPOWER


K&N® performance cold air intake systems are designed to provide a smooth, unimpeded path for the airstream—helping keep airflow cooler and more oxygen-dense. With a K&N® performance air intake system, you get a guaranteed increase in horsepower and torque.

PROTECT YOUR ENGINE


Poorly filtered air can result in severe internal engine damage, and can degrade valves, cylinder walls, and pistons. 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. All K&N® filter designs are tested according to ISO 5011 testing protocols, ensuring exceptional engine protection for your engine.

IMPROVE ENGINE SOUND


Factory systems often feature intake tubing with tight bends, baffles, and other obstacles that can slow airflow and create turbulence. These systems are also typically designed to muffle engine noise—unlike K&N® cold air intakes, which are designed to give your engine a more satisfying growl on acceleration, yet stay quiet once at speed.

CUSTOMIZE YOUR ENGINE BAY


K&N® offers several performance cold air intake system options to cater to different aesthetic, ease of maintenance, and filter media preferences. Choose among mandrel-bent aluminum, powder-coated aluminum, and high-density polyethylene intake tubing, and select either an oiled cotton High-Flow Air Filter™ or non-oiled synthetic DRYFLOW® air filter (options vary by vehicle).

GO GREEN


If you assume an engine life of 300,000 miles—and replace your disposable air filter every 15,000 miles—only one K&N® air filter will be used during the same period in which twenty disposable air filters will be discarded. K&N® stands behind its 10-Year/Million Mile Limited Warranty—High-Flow Air Filters™ have been tested functional even after a million miles of use. One industrious driver put K&N’s warranty to the test, and his filter was still providing exceptional engine protection even after one million miles of use!

Our Story

Why K&N?

K&N is the home of the original red oiled air filter. In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an oiled air filter. Five decades later, K&N® is still innovating industry-leading filtration technology, and offers outstanding protection for everything from top-fuel dragsters to commuter vehicles across the globe. Thank you for helping us reach 50 years in business!

“ALL I CAN SAY IS WOW. THERE’S A HUGE, DRAMATIC DIFFERENCE ON THE THROTTLE RESPONSE-I FELT IT IMMEDIATELY.”

FREQUENTLY ASKED QUESTIONS

   

K&N offers a guaranteed increase in horsepower and torque for all K&N intake systems. Dynamometer tests indicating estimated horsepower and torque increases compared to the OEM intake system will appear on the "Product Details" page for each performance intake system. Results will vary.

No. In the United States, in order for the manufacturer of a warranted product to void or deny warranty coverage of a repair due to the use of an aftermarket part, the manufacturer must provide proof that the aftermarket part is the cause of the necessary repair. These rights are protected under the Consumer Products Warranty Act of 1975 (also referred to as the Magnuson-Moss Warranty Act).

K&N® cold air intake systems allow for increased airflow to your engine, which results in an increase in horsepower and torque.

K&N® performance air intake systems are designed to create a less restrictive path for airflow to reach the engine by removing the stock intake tubing that can increase restriction, and also by utilizing high airflow filter media.

In a K&N cold air intake system, air first passes through a performance air filter—typically a High-Flow Air Filter™, which is designed to provide up to 50% more airflow than a disposable paper filter—and then passes through a specially designed tubing system that helps provide a smooth path for airflow.

Roto-Molded High-Density Polyethylene (HDPE) Intake Systems: 57-Series, 63-Series

High-density polyethylene (HDPE) rotationally molded tubes help increase the volume of airflow to your engine, and provide a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield or air box helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.
*Certain 57-series and 63-series intakes are designed to function with the factory air box, and feature a panel filter paired with a custom roto-molded intake tube.

Mandrel-Bent Aluminum Intake Systems: 69-Series, 77-Series

Mandrel-bent aluminum intake tubes help provide an increase in airflow to your engine, and each 69-series and 77-series intake system offers a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter™ featuring oiled cotton filter media, and the oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A steel heat shield helps protect intake air from the high temperature of your engine bay, and the system can typically be installed in less than 90 minutes.

Blackhawk Induction™ Air Intake Systems: 71-Series

Blackhawk Induction™ air intake systems feature an oil-free synthetic filter media, black powder-coated aluminum intake tube, and all-black components. The layered DRYFLOW® synthetic filtration media provides increased airflow and exceptional engine protection without requiring oil, and a steel heat shield helps protect intake air from the high temperatures of your engine bay. The system can typically be installed in less than 90 minutes.

K&N® does not make any claims or guarantees in terms of increased gas mileage with the use of K&N filters or intakes, due to a vast number of variables that can affect a vehicle’s gas mileage.

An internal combustion engine operates by burning a mixture of fuel and oxygen within the engine’s cylinders. The fuel injectors provide a precise amount of fuel, which combines with air delivered by the air intake system. A spark plug then ignites the volatile gas, creating an explosion that forces the piston downward—turning the crankshaft. The piston-moving force that’s created during the combustion cycle is what produces horsepower. K&N performance products are designed to increase the efficiency of your engine’s combustion process.

Once you determine that the filter included in your intake kit needs to be cleaned, K&N® air filter cleaning products help restore your air filter to like-new condition. There are specific cleaning products for each type of filter. Follow this linkto view complete cleaning instructions and available products.

Maintaining the proper air-to-fuel ratio (AFR) is critical for engine performance, and relates to the amount of air versus the amount of fuel used by an engine for combustion. A correct, stoichiometrically balanced AFR produces combustion with perfect efficiency, excluding other factors. For gasoline engines, the theoretically perfect chemical ratio is 14.7 : 1—14.7 parts air to one part fuel. In effect, this means that an engine requires almost fifteen times more air than fuel for efficient combustion—which emphasizes the importance of providing a high volume of air through an intake system.


*K&N intake systems are compatible with vehicles with a suspension lift installed.

At this time, it is not recommended to install a K&N® intake system on a vehicle with a throttle body spacer. A throttle body spacer will move the opening of the throttle body away from its stock location. Since K&N develops intake kits on vehicles with a throttle body in the factory location, the addition of a spacer would add length to the intake tube, pushing it away from its mounting points—and possibly causing the tube to come loose, come into contact with the hood or other engine components, or even break. In most cases, serious modifications would be required to make the kit work, and such modifications would void the 10-Year/Million Mile Limited Warranty.
