## Polini Air Filter Insert - Superior Performance for Your Scooter The Polini air filter insert brings knowledge straight from the racetrack to your scooter. It ensures optimal engine performance and protects it from contaminants. This efficient sponge filter, made of flexible polyurethane foam with a mesh polyester base, consists of two layers of foam: blue with a fine porosity of 60 PPI and black with a porosity of 30 PPI. ### Two-Stage Filtration for Maximum Protection The blue layer filters the finest dirt particles, protecting the engine from premature wear. The black layer stops larger contaminants, acting as the first line of defense. The wavy outer surface ensures high airflow, capturing up to 50% more large dirt particles. ### High Efficiency and Long Service Life The Polini air filter insert meets the European standard EN779 (G3 to G4), guaranteeing filtration efficiency of over 90%, and for particles with a size of one micron - over 50%. The filter is also characterized by a high dust holding capacity, which translates into a longer service life. ### Easy Maintenance and Regeneration The filter insert should be soaked in special oil for sponge filters. It is possible to regenerate the filter by washing and drying, which allows for its multiple use. Replacing the original air filter insert with Polini improves airflow during intake, optimizes the fuel-air mixture, and increases engine power. ### Compatibility and Fit The Polini air filter insert is available for various 50 cc scooter and maxi scooter models. Before purchasing, compare the shape of the filter insert in the photo with the shape of the original filter. Regular replacement of the air filter insert (every few thousand kilometers) affects fuel consumption and the life of the scooter. Choose Polini - quality and performance straight from the racetrack.
