well after my studying from last night.
I think the price should land somewhere from $700-$1000USD
because on the N54/55 there is an additional pipe that is needed.
$700 is just for the kit itself.
Aquamist sells their own kit fo $900 so....
my question now is when can this be delivered I'm very curious to try it out of my boosted M3
