Frequently Asked Questions


No. In the United States, in order for the manufacturer of a warrantied 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).

Performance intake systems are legal for street use in most areas of the United States. In California, and in specific regions which have adopted California air quality regulations, only CARB-exempt performance intakes are legal for street use. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

It is possible that the Check Engine Light may come on after installing a K&N air filter or performance intake system. This does not necessarily mean that there is something wrong with your air filter or intake; sometimes, the higher air flow and lower restriction provided by the K&N product will uncover an existing mechanical or electronic issue with your vehicle. In rare cases, you may have a K&N product which was manufactured outside of its design tolerances, causing sensors in your vehicle to read data outside of their normal expected values. In either case, the K&N Warranty Department can work with you to narrow down the cause of the Check Engine Light and correct the issue.

Dynamometer tests indicating horsepower and torque increases over the OEM intake system will appear on the "Product Details" page for each of our performance intake systems.

Cold air intakes allow for increased airflow to your engine, which results in an increase in torque and acceleration for your vehicle.

In theory, a cold air intake could increase the gas mileage of your vehicle due to improved airflow which allows the engine to run more efficiently and require less fuel. However, K&N does not make any guarantees in terms of increased gas mileage with the use of our filters or intakes.
