Product Introduction

The Breather Tube (3971371) is a component of the truck's engine ventilation system. It is responsible for allowing air to enter and exit the engine's crankcase, which helps prevent pressure build-up and ensures proper lubrication of the engine's moving parts. The tube is typically made of durable materials such as metal or plastic, with a design that allows it to withstand high temperatures and exposure to various chemicals found in the engine compartment. Over time, breather tubes may become clogged with debris or wear out due to age and need to be replaced for optimal engine performance.
