My housing was from 2010. The spin on solution uses oil filters that also have a pressure relief valve installed in some cases, which already opens at lower (!) or similar overpressures. Furthermore, the original housing is made of glass fiber reinforced nylon (PA66 GF35). I was about to shoot the original housing and a spin on filter with an air rifle. I could not yet bring myself to do this, have no spin on filter anyway. But: I trust the tough original housing more than a thin sheet metal jacket when hit by stone etc.

So at this point, I really can't see any advantage anymore, besides, the original filter insert is much easier to check for chips and waste is also minimized.

Btw, the valve can be pulled out and put in again without destroying something, it's just clicked in.
