air filter Polini D.37 small air box 37mm 90° black

Polini's Racing Boxed air filters are ideal for daily use in various weather conditions, as well as being used on the race track. Because with the additional dirt or water protection cap, this tuning air filter becomes a real all-rounder.
Specifically, foam tuning filters are very susceptible to moisture, and the protective cap prevents the filter from draining quickly.

• Suitable for: PHBG Racing Carburettors
