Breather Plug

About this product

The Breather Plug (#90930-03127) is a critical Drive-Chassis component found in the Rear Axle Housing & Differential system of your Toyota vehicle. Its principal function is to allow the escape of any internal pressure built within the system while prohibiting the ingress of contaminants. It achieves this by utilizing a simple but effective valve mechanism. Over time, this auto part can become clogged or damaged, hindering its ability to function appropriately. A non-functional breather plug can lead to a buildup of pressure within the axle housing, potentially causing oil leaks or even damage to the seals and bearings. Therefore, periodic replacement of this component is essential. When replaced with a genuine Toyota part, you not only assure compatibility with your vehicle but also benefit from the peace of mind provided by Toyota's genuine parts warranty. Ultimately, a functional Breather Plug (#90930-03127) contributes to the preservation of the Rear Axle Housing & Differential system, enhancing overall vehicle safety and efficiency.
