Yeah, OEM intake hose eventually splits. Mine even split back with my OEM airbox, don't know how that happened?
Judging from where the crack was and fracture pattern, it may have been due to engine movement and vibrations because there was a point in time where I had to drive with broken engine mounts while I waited for my order to arrive.
Didn't know it was broken until a few months after so that's just a theory.
