Hello All, Happy Summer!

I have a question: I was reading older post about the oil separater box replacement versus cleaning.
It seems from what I could garner that replacement is more effective, though costly.
If replacement is the way to go this raises the question of which OEM box to buy. On eeuroparts they have one labeled OEQ 3501160. WOndering if ithis is a decent one or if there is one better than this. WOuld rather not go to dealer to buy it as that gets mighty expensive and time-consuming.

I am asking becuase I have replaced my flame trap hose twice in the last two years, each time if was split in the lower section which I am surmising to mean the separater box is not operating correctly.
