What makes K&N the Best in the aftermarket?

All K&N products undergo rigorous testing to ensure that they adhere to demanding quality standards. We stand behind our products with some of the most extensive warranties in the aftermarket.

HORSEPOWER TESTING
Horsepower and torque claims are based on testing of an actual vehicle on a dynamometer before and after a K&N product has been installed. Horsepower/torque testing is performed on Dyno Jet 248 and SuperFlow 880E dynamometers, which measure actual brake horsepower and torque at the wheel(s) receiving power from the drive train.

AIRFLOW TESTING
K&N performs all airflow testing on a SuperFlow Corporation SF-1020 flow bench. The SF-1020 is a computerized flow bench capable of measuring airflow rates up to 1020 cubic feet per minute (cfm) at test pressures of up to 65 inches of water.
