Considered it for my Montero. But, with the 4x4 I do, it could be a weak link. I wanted to put an inline filter on my transmission and my mechanic did not recommend it. As it could be a weak link and isn't necessary. I figured if it were necessary, the Japanese engineers that designed would have included it. They over engineered my particular model. Just luck for me!
For everyday driving you should be ok. Let us know if you decide, they are not expensive. There's even a pic of one being cut open.
Respectfully,
Pajero!
