Guaranteed Horsepower with K&N Cold Air Intakes

K&N is clearly the defined leader in high quality performance cold air intake systems for car and trucks. We feel it is one of the best dollars to horsepower investments you can make for your vehicle. Our first air intake kit was built in 1992. K&N manufactures over 500 different part numbers and our team of engineers are constantly designing, building and testing new air intake systems.

50 State Street Legal Air Intakes

Many K&N air intake systems are street legal in all 50 states and include a California Air Resource Board (CARB) Executive Order (EO) number that ensures the intake kit has been tested to comply with emissions standards. EO numbers apply to the kit as well as the year, make and model it is being installed on. Air intake systems with no EO number are street legal in most states but may not be used on emissions controlled vehicles in the state of California or other states adopting California emission standards. Use K&N's search by part to see which cold air intakes are CARB exempt and for which vehicles.

K&N Million Mile Limited Warranty

K&N invented the world's first air filter that is guaranteed for one million miles. That same great warranty applies to our high-flow air intake systems. Our performance products are well engineered, built with the finest materials and we stand behind them 100%. View our warranty page for further details.

K&N Air Intakes are Easy To Install

Does installation of a K&N cold air intake system sound complicated? That's the great part, our air intakes are very easy to install on your car or truck. A typical air intake installation can be done with a screwdriver, pliers and a ratchet-set in 90 minutes or less! We specifically engineer our intake kits to use existing factory holes and mounting points, making installation simple. The vast majority of our cold air induction systems do NOT require any cutting or drilling.

K&N 57 Series Fuel Injection Performance Kits (FIPK)

K&N 57 Series Fuel Injection Performance Kits (FIPK)

K&N 57 Series FIPK Air Intake Kits represent a dramatic performance improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded intake tubes that can reduce air temperature and decrease sound over a metal tube. Air flow restriction can exist between the air filter and engine reducing the benefits of a K&N performance air filter. K&N air intake kits virtually eliminate restriction in the air path by replacing the filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which in turn adds power.
K&N 77 Series High Performance Air Intake Systems

K&N 77 Series High Performance Air Intake Systems

K&N 77 Series metal air intake kits combine outstanding performance and style for trucks and SUV's. Many K&N air intake owners opt for the visual appeal of these systems. These K&N 77 series cold air intakes come with grey and chrome-like intake tube finishes.
K&N 63 Series AirCharger® High Performance Air Intakes

K&N 63 Series AirCharger® High Performance Air Intakes

Restriction is often found between the factory air filter and the engine which can reduce the benefit of a K&N air filter. K&N 63 Series air intakes virtually eliminate air path restriction by completely replacing the air filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which translates into an increase in vehicle horsepower.
K&N 69 Series Typhoon® Air Intake Systems

K&N 69 Series Typhoon® Air Intake Systems

K&N Typhoon® air intake systems are built for performance and show. This free-flowing mandrel-bent aluminum tube induction system was designed to fit many sport compact performance vehicles. Typhoon air intakes come with a high-flow conical air filter designed to provide increased surface area and dust capacity. Some Typhoon air intakes are not legal for use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N air intake product page for specific CARB status.
K&N Blackhawk Induction™ Air Intake Systems

K&N Recreational Vehicle Air Intakes

K&N Recreational Vehicle Air Intakes

K&N RV and motorhome air intakes are guaranteed to increase horsepower. While going up a steep hill or getting up to speed on the freeway, extra power from an RV air intake system can always be used. The factory air filter and air path in these moto homes can be very restrictive. K&N RV and motorhome air intake systems are designed to provide excellent filtration and less restriction, resulting in additional horsepower.
K&N 57S Performance Airbox

K&N 57S Performance Airbox

K&N 57S Performance Airboxes are special air intakes developed by K&N, the inventor of the million-mile high-flow air filter. These air intake systems increase horsepower and acceleration by dramatically reducing air flow restriction caused by the original factory design. A K&N 57S intake system completely replaces the factory air box and air filter with upgraded high quality components. The 57S air intake assembly is large enough to house an oversized conical air filter and the entire product is backed by our Million Mile Limited Warranty.
K&N Apollo Universal Closed Intake Systems

K&N Apollo Universal Closed Intake Systems

K&N Apollo Closed Intake Systems are universal air intakes incorporating a high flow air filter and closed filter housing. The specially designed shape of the Apollo air intake system increases volumetric efficiency and provides the benefits of an open cone filter element and standard air box in one unit. Heat buildup is reduced which keeps the intake charge cool while the smooth internal features minimize air turbulence and maximize air flow.
K&N 57i Performance Induction Kits

K&N 57i Performance Induction Kits

K&N 57i Gen I air intake systems are a great way to maximize airflow and engine performance. As with all K&N air intake kits, when you bolt a 57i air intake to your vehicle, you will notice the difference in performance the next time you drive. The combination of high flow air filter technology and larger air filter size will increase vehicle horsepower and sound great too. K&N 57i cold air inductions systems also come with a washable and reusable air filter.
K&N Cold Air Intake Reviews

K&N Cold Air Intake Reviews

"Installation time and procedure in my Audi was exactly as stated.  No surprises. Noticeably improved throttle response with the K&N cold air intake versus the stock airbox. Definitely recommend this upgrade."
