Gilera Runner 50cc Polini Air Filter

Doublelayer air filter (Double Layer), which fits in the original filter box.
Original Polini intake system, which replaces the paper filter with a larger surface of its double-layer foam. Fits perfectly in the box like the original, due to its original-type plastic body.
But making the Racing difference with the special Polini foam with different densities. One for greater particle filtration and a second for greater intake.
Good replacement, with a certain quality for your scooter.
