AIR FILTER DOPPLER "AIR BOX" BLACK MOTORS MINARELLI & PIAGGIO Ø28-35mm

The DOPPLER Air box air filter combines efficiency, filtration and low noise pollution, and is a major technological advance.

Indeed, extreme development on the test bench and in road use has allowed DOPPPLER to obtain results far above the products available on the market.

This system uses the principle of forced air used in motorcycles using venturi tubes.

This principle accelerates the speed of the gases and therefore significantly increases the filling of the engine.

In addition, other important factors taken into consideration such as noise and filtration set this product apart.

On the one hand, the inclination of the venturi tubes reduces the noise level of the intake.
On the other hand, the efficient filter element reduces dust penetration, limits engine wear in order to maintain a stable level of performance over time.

Inside the box, the filter elements are arranged diagonally, which allows a larger air passage surface.

Fully disassemblable, this product can be maintained.

Finally, this box can be used on the original carburetor or with larger carburetor diameters.
