MIA's Description

The UNIFILTER NU-3243ST is a dual-stage foam air filter designed for competition motorcycles. It features a unique two-stage design that allows for easy and complete cleaning. The outer layer can be used dry as a pre-filter for longer intervals between cleanings, or it can be oiled for superior engine protection in wet conditions, while the inner filter must always be oiled.
