My tubing cinched on me while routing up into my engine bay. Very difficult to work out once it cinches. For this price point I expected better material and for issues like this to of been worked out.

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

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.

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
