Review on ARB 170112 Differential Breather Kit by Antonio Taveras

Perfect fit for my 2019 Toyota 4 Runner. Installation was easy and effortless and the threads matched the threads on my rear differential. The pipe was sufficient for the rear differential and electronic locker, although I had to purchase an extension hose coupler to connect the ARB pipe to the original electronic locker vent pipe. Not a big deal since the local auto shop was selling the package for less than $2. The block and filter were simply mounted high up on the side panel of the engine bay just behind the airbox/intake. The installation may have taken 30 minutes. Quick tip: start routing pipes from the engine bay down and back. When making Elocker and Diff you simply fold the tube in half and attach as one piece, then simply cut/split at the back to make two joints. I considered just running a hose to the filter and then using a splitter/tee at the back, but wasn't sure if that was a good idea. I assume running two lines at least allows things to be separated.
