ARB 170112 Differential Breather KIT Vent The air Pressure in drivetrain Assemblies Such as The differentials, Transmission and Transfer case.

I installed the breather in the engine bay and ran hoses back to the rear differential and rear differential locker breathers on my 2023 Toyota 4Runner ORP. It was a straightforward install, my advice would just be to take your time and double check how you route the hose, you'll want to steer clear of exhaust components.

Worked perfectly for my 2019 Toyota 4 Runner. The install was wuick and easy and the threads matched the ones on my rear differential. There was enough tube to do the rear diff and e-locker, though I had to buy an enlarging hose coupler to join the ARB tube to the OEM e-locker breather tube. No biggie as it was less than $2 for a pack at the local auto store. The block and filter were easily mounted near high on the side wall in the engine bay just behind the air box/intake. Maybe took 30 mins to install. Quick tip: start running the tubes from the engine bay, down, and back. Also, if you're doing elocker and diff, just fold the tube in half and run/secure it as one then just cut/separate it in the rear to give u the two connections. I thought about just running one tube to the filter then using a splitter/T-coupler in the rear, but I wasn't sure if that was a good idea. I guess running two lines will at least keep things separate.

The arb diff breather kit Includes all parts, Was straightforward and simple to install. Plenty of tubing is provided for most off road platform applications .Now both my front and rear solid axles have a central manifold for fresh air in the engine compartment . Preventing any deep water crossings from letting water enter the axles . I installed these kits on two vehicles . Both Landcruiser's (60 series ) fj62, (80 series) fzj80.

Did the update on 4runner rear differential. Did not use the self threaded bolts that come in the kit. Bought an M6 bolt and bolted the manifold to an existing threaded hole in the passenger side of the engjne bay, next to the air filter. Comes with 4 plugs for two breathers but can buy extra plugs since manifold holds up to 4. Video overview on how to below.https://youtu.be/Ob6oHB7vaGE?si=2yMG20bfem79G_0o

Easy install.

Working great on my nissan patrol y61

The included screws are so short, there is zero thread past the thickness of the breather valve body. lol.With that oversight mentioned, the rest of the kit is great. Just used 3m automotive tape to hold it in place behind the tail light

Excellent diff breather kit. The kit includes four push-to-connect threaded hose connectors, which conveniently fit as a direct replacement for the 04 Nissan Xterra breather. My OEM breather was severely clogged and rusted, which likely was the cause for my rear pinion seal leaking.
