Car : AUDI, A6, 3.0 supercharged. V6. Quattro. So much of the different when I installed K&N E-1983. With full gasoline tank, I gain more distance in travelling as compare to the orginal air filter original from OEM.
Wong Ivan, Singapore
Works great. I haven't driven the car much since I'm still getting it up to snuff. It was neglected for many years before I bought it. Car (1990 Audi 200 quattro turbo) pulls a little harder now but I bought it mostly for ease of cleaning and the infrequent cleaning intervals. These cars have a difficult-to-reach airbox.
