## Overview

The Purolator B43127 Breather Filter is a vehicle-specific emission control filter designed to trap harmful contaminants from entering the engine crankcase. Working in tandem with the PCV valve, it ensures clean airflow, preventing engine damage caused by dirt and vapors. Compact yet essential, this high-quality filter offers a precise fit and reliable performance, backed by strong customer satisfaction.

## Description

Breathers, also known as emission control filters, filter fresh air that's drawn into the engine's crankcase. Because the engine must breathe to purge itself of fuel and water vapors, breathers are used in conjunction with the PCV valve. Although small in size, Purolator breathers are big in importance. Like any other filter, the breather is used to trap harmful contaminants and prevent them from damaging the engine. Failure to change the breather will allow unfiltered air (with all of its contaminants and dirt) to be drawn into the engine crankcase which can cause engine damage.
