Air Filter Doppler Venturi 28/35mm PHVA/PHBN black

Air filter Doppler Venturi 2010 white

The standout racing air filter is Doppler’s Venturi-Air system. True to its name, it uses the Venturi principle, which means the intake narrows at a certain point, reducing the vacuum needed to pull in air. On 50–70cc engines, too small or too large an intake requires higher vacuum, which limits performance.

The Doppler Venturi-Air system draws air through a Venturi insert into a resonance chamber. This chamber smooths out pressure pulses and intake noise, letting the carburetor run more evenly and making tuning easier. The slightly redesigned intake path also makes the filter quieter than before.

We recommend that you order a carburetor jet set to optimally adjust the carburetor to this pod air filter.
