Super Jet Speedwerx pipe water routing

[Waternut]

Can anyone confirm or deny what I'm suspecting is the water routing for this pipe?

1 & 2: inlet from the pump
3: inlet from the head
4 & 6: connect together to cool the waterbox
5: outlet to the pisser

you are correct

If your in cold water and run it direct into #3 it hits a touch harder. with ECWI doesn't matter
