Air Filter with adapters Polini Big Evolution 25 - 55mm

Polini Evolution round pod air filter

The foam air filters feature a significantly larger intake surface compared to original air filters, resulting in improved cylinder filling and overall performance.

The main jet should be increased by a few sizes to prevent the mixture from running too lean and causing the cylinder to overheat. We recommend ordering a carburetor jet set to optimally adjust the carburetor to the tuning air filter.
