Guaranteed Horsepower with K&N Cold Air Intakes
K&N is clearly the defined leader in high quality performance air intake systems. 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. 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.
