K&N E-3980 Air Filter Product Reviews

Wednesday, June 22, 2016 - Part E-3980
I had a (Brand Name) filter on my 2003 HD Electra Glide Ultra Classic TC88 but it did not idle good. I saw the ad for K&N increases horsepower and torque with almost 10 hp and 10 ft lb of torque. It is idling better and more responsive on the throttle. I will see if it helps my gas mileage? Which it should since I am getting more air.
