    Lightweight, great fit, awesome price!

    Better than stock filter. Spray foam filter oil on it and it's good to go. No problem installing it on my 1981 Honda ATC 110.

    Works for my 83 honda atc 200e

    Great replacement filter. Isn't the same length as the one filter. But I pushed it on and it works. It could be cut to fit

    Does a good job keeping the dirt out of the engine.

    It fit perfectly on the stock air filter assembly.
