## Overview

The Uni Filter NU-3218ST is a high-performance foam air filter engineered for Yamaha YFZ 450 models from 2004 to 2015. Utilizing open-cell polyurethane foam coated with specialized filter oil, it traps dirt efficiently across its entire thickness, preventing airflow restriction for up to 80% of its lifespan. This washable and reusable filter ensures sustained engine performance while reducing maintenance costs, making it a top choice among powersports enthusiasts.

## Description

UNI AIR FILTERS.The principal of how foam air filters work is simple: "Open Cell" polyurethane foam is wetted with specially developed filter oil.The "sticky" filter oil is suspended in the path of the dirty air on the strands of the web-like cell structure of the foam.This makes it impossible for the dirt to pass through the strands.As the outer strands become loaded with dirt particles, the wetted strands down stream start trapping dirt, allowing the entire thickness to be utilized.This prevents surface loading or air restriction for 80% of the surface life of the air filter element.When the filter is sufficiently dirty it can be easily washed, re-oiled and re-used.
