Venturi Air Filter from DOPPLER - streamlined tuning air filter with clever flange system and significantly reduced noise.

The Venturi air filter from DOPPLER tapers towards the Carburettor, which accelerates the mixture and effectively supports the intake process - comparable to a compressed garden hose from which the water emerges at a higher pressure. In close-to-production Engines, a single passage opening remains active; in tuned setups, an additional predetermined breaking point can be opened, which significantly increases the air flow rate.

A sophisticated flange system ensures that the filter fits carburettor sizes from 17.5 to 25 mm, making it interesting for many tuning configurations. In addition to its striking appearance, the Venturi air filter is particularly impressive acoustically: it is significantly quieter than most comparable sports and Racing Air Filters on the market and thus combines performance with a background noise level suitable for everyday use.
