Polini straight air filter

Straight Polini Airbox competition air filter.

Competition filters have a considerably larger surface area than original filters. The intake sound is louder.

You should increase the size of the main jet in the carburettor slightly, so that the mixture does not become too lean.

Choose between the short version (60mm) and the long version (95mm).

Check the measurement of your carburettor's inlet to choose the correct diameter.

• 32mm for Dellorto 19-21 carburettors
• 36mm for Dellorto 12-17 and Amal 17-21 carburettors
• 39mm for Dellorto 24-26 carburettors
