I was looking into getting a GK tech swirl pot to help reduce temps on my ‘09 370Z. It seems to be the consensus that the newer pressurized reservoirs do not need/benefit from this setup. I think it’d be a cleaner install to switch over to the newer coolant reservoir style instead of adding additional hoses in the engine bay to mount up a swirl pot with my early style reservoir.

Can anyone elaborate on the differences in the two styles/systems? Specifically, where does the bottom hose of the newer style reservoir lead? (This isn’t present on the early style) Am I right to think it’d be simpler/cleaner to change reservoirs instead of adding a swirl pot?
