Righetti Ridolfi Active Air Box

Righetti Ridolfi Active Air Box

The filter cartridge used for the Active noise filter is made of polyester and can be cleaned with solvents, gasoline and compressed air.
This cartridge has a filtering of particles of more than 10µm (10 thousandths of a millimeter) and it is evaluated as the best compromise between air flow and air cleaning.
10µm value allows also the filtering of the impurities produced from the front brake system: it is usually between 15µm and 30µm and it is know these impurities are very aggressive with the inside parts of the engine.
The new cartridge has a reed barrier to modify the air flow and reduce the turbulence inside the airbox.
The new inlet pipes have a better Venturi effect that result in better performance.
