Been contemplating the idea and not sure what to make of them. Apart from being an extra shinny accessory, are they really an extra worth having.

I understand the principals of how a swirl pot works, and in theory it sounds to be a good extra. But from my understanding, doesn’t the thermostat housing act like a sort of swirl pot, by extracting air back into the headertank.

Just wondered what peoples views were on them, are they worth putting on or are they just really a extra shiny show piece.

If they are considered to be a good extra, do you guys a) blank of the top of the thermostat housing and run the one hose from the header tank to the top of the swirl pot, or b) providing the headertank has two breather ports, run one hose to the top of the thermostat housing and the other hose to the top of the swirl pot. What’s the better method!!!
