Description

Carburettor connection D.55-49-45-42-35-28 EVOLUTION and BIG EVOLUTION AIR FILTERS The EVOLUTION and BIG EVOLUTION air filters are components of fundamental importance in the set-up of a racing engine to better optimise engine carburation. The special sponge guarantees a high filtering capacity that allows air impurities to be trapped but, at the same time, allows a large air flow to pass through. The cylindrical with off-centre sleeve shape for the EVOLUTION filters and the truncated cone shape for the BIG EVOLUTION models allow easy fitting, adaptable to any type of scooter. BIG EVOLUTION filters are supplied complete with a set of sleeves of different diameters adaptable to the most common carburettors.
