The Polini Evolution nozzle ensures shorter travel from the carburetor to the engine, this is extremely useful on Racing cylinders which take many revolutions - and also helps to improve the response. Unlike the original spigot, it faces straight back and it is therefore not possible to use the original air filter. The feed rate is 24mm and the nozzle can therefore be used with 19-21mm carburetors.
