Polini have improved their 'Big Evolution' air filters to better exploit engine carburetion.
The air filter pictured above (Polini product code: 203.0159) features a 'truncated cone' shape, it's easy to fit and is suitable for Yamaha Minarelli horizontal engines equipped with a Polini PWK carburetor. The sponge has a high filtering capacity which traps all the impurities in the air while allowing air to flow efficiently through to the carb.
The above air filter (Polini product code: 203.0160) again has a truncated cone, it's easy to install and comes with a set of sleeves of different diameters to allow fitment with most of the popular carbs.
RRP for the above products: 38 Euros (£30.59) + VAT
