Highly recommended
A must-have upgrade for serious off-roaders and overlanders. Reliable, well-built, and worth it for the protection it provides.

Works well, you'll want a small mod if you have a 4runner with a rear locker
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.

A must have for water crossings and muddy terrain
If you go offroad and have to traverse water crossings, this is a must have. It allows re-routing the differential breather from the top of rear diff to anywhere in the engine bay. Comes with very long hose, so can fit truck of any size. This will save your rear diff by not allowing water to be sucked in if diff is hot and water is cold.
