POLINI AIR FILTER APRILIA SR 50

The POLINI air filter is designed to ensure superior performance in the most popular 50 cc scooters and maxi scooters. Made from flexible expanded polyurethane foam with a reticulated polyester base, this filter consists of two distinct layers: a fine blue layer with a porosity of 60 PPI and a more open black layer with a porosity of 30 PPI.

The two-layer structure allows for effective filtration, where the fine layer retains only the smallest particles, preventing contact with larger particles that have not passed through the pre-filtration. The wavy outer surface promotes greater airflow while retaining 50% more coarse dust.

This filter meets European regulations EN779 of grade G3-G4, with a weight efficiency of over 90% and an effectiveness of over 50% in retaining 1-micron particles. Additionally, the ability to retain dust is further enhanced by the use of a specific oil for foam filters, and the filter is regenerable and washable, ensuring a long lifespan.

By replacing the original filter with the POLINI air filter, airflow during the intake phase is optimized, improving the air-fuel mixture and increasing engine performance. With POLINI, a simple filter change can transform your riding experience, leading to a tangible increase in power.
