Why Extend Your Nissan Patrol or Safari Diff Breathers?
As your vehicle is driven, the differentials, gearbox and transfer case heat up. This causes the air inside these components to expand and vent through their factory breathers.
When a hot differential enters cold water, the air inside cools and contracts quickly. If the factory breather is submerged at this point, the resulting pressure difference may allow water, mud or grit to enter the drivetrain.
Relocating the breathers higher in the engine bay provides a cleaner and drier location for them to vent. This helps protect your drivetrain oils and internal components during water crossings.
Protected Breather Housing
The supplied breather housing helps shield the filters from direct splashes, mud and dust inside the engine bay.
The cover can be easily removed when the breathers need to be inspected or cleaned.
Installation
Installation generally takes approximately one to four hours and can be completed using basic hand tools.
Depending on the exact vehicle and existing breather arrangement, drilling and tapping a thread may be required to install some fittings. Check the installation requirements before beginning, or contact us if you need advice.
