Customer Review

“Extremely happy with this product. Not only have I seen an increase in torque, but also hp & fuel efficiency. I work at Harley Davidson and after installing the filter, I put my bike on the dyno. As stated in the description, this intake is already dyno tuned. I did not have to make a single adjustment. I will be purchasing this again, when I get my new road glide.”

Frequently Asked Questions

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).

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.

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.
