Malossi is a leader in high performance parts for scooters so it only makes sense that their air filters are some of the best performing I have come across.
There is a difference is all filters and mods. The cover over this filter does wonders for tunning and adjusting air flow.
The "boxed" Racing Air filter Malossi is a "wrapped" air filter variant to protect the filter element from dirt and water.
In addition, the noise level is slightly reduced and the filter is, for example in the black version, very unobtrusive. Even the boxed version can be opened carefully, rinse the filter element and oil can be added.
The filter is slightly angled and has a 38mm carburetor connection. This makes it suitable for all and Dellorto carburetors from 12 to 21mm for Dellorto and Arechee. Also fits Arreche to 21mm. Can of course also be mounted on other carburetors with 38mm connections.
