Many of the accessories you think are new ideas, actually date back many years. This definitely applies to wind deflectors, the first versions of which started to appear in the 1940s when the accessory market in the US started to grow.
These new wind deflectors from Paruzzi are clamped to the vent window and diverts the wind when the vent window is open, creating a suction effect to improve ventilation. The first advertisements to appear for this accessory were mainly aimed at smokers because of the sucking effect, with cigarette smoke disappearing more quickly.
Nowadays it is a retro fitted accessory where the real function is no longer so important, hence they are also available in various transparent colors and for the chrome lover, in polished stainless steel.
Please note these items are delivered as a pair.
