The coolant adapter with fill port is not made correctly and the fill tube will not sit vertically at the correct angle. The price is nice and it functions correctly but it drives me nuts. I'm gonna end up having to purchase the K-Tuned version. Also being a cheap Chinese knock off you can find this exact version cheaper than the bull boost stamped unit.
I gave it 2 stars rather than 1 because It does make bleeding a K20/K24 super easy.
