Review: Good quality easy install - ARB make some good stuff and this is no different. The 2 sheet metal screws are short so I chucked them and use stainless nylock and bolt. Much more secure. I put mine behind my passenger taillight as high as I could. Getting a drill in wasn’t easy but it worked. I took my time running the hoses to make sure they are hidden and away from damage. Happy the way it turned out but seeing how it actually works in mud and water will determine my over all satisfaction.
Review: Awesome product - Worked great! I connected the front and rear breathers together at the manifold. I positioned the breather in the engine bay. Great product

## Features

- ABOUT ARB 170112: The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water. This is achieved with a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.
- CONSEQUENCES OF NOT HAVING ARB 170112: When drivetrain assemblies such as your vehicle’s differentials, gearbox and transfer case heat up under normal operation, the air inside expands and increases pressure, not suitable for the vehicle. The ARB Differential Breather Kit is designed to provide a high-flow, zero back pressure, zero vacuum breather system to keep your drivetrain free of water.
- HOW DOES DIFFERENTIAL BREATHER KIT WORKS: It uses a central high-flow air filter and manifold that will allow up to four drivetrain assemblies to be vented to one central location, positioned high enough to avoid water during crossings.
- PREVENT WATER FROM CONTAMINATING COMPONENTS: The ARB Differential Axle Breather Kit eliminates water from contaminating the oil and damaging your drivetrain components by providing a high flow, with no back pressure, zero vacuum breather system.

### ⭐⭐⭐⭐⭐ Awesome product
*by D***E on December 4, 2025*

Worked great! I connected the front and rear breathers together at the manifold. I positioned the breather in the engine bay. Great product

### ⭐⭐⭐⭐⭐ Works well, you'll want a small mod if you have a 4runner with a rear locker
*by A***S on June 18, 2025*

Easy install on a 5th generation 4runner. There is a 6mm threaded pitch hole on the passenger side of the engine compartment that works well for the bottom bolt of the manifold, then just use one of the self-tappers included to lock it into place. I went ahead and grabbed some t-barbs and waterproof tape to add a junction to the breather just above the rear differential so I could also extend the breather for the rear locker. https://amzn.to/408wvRq and https://amzn.to/3SXF25P Took me about 30 minutes total, easy mod that will set your mind at ease so you don't go polluting your gear oil or blow out your seals.
