This started off as a one off product that we ended up with a couple extra of. Its a -20 stubby "waterneck", this will not work with a standard location turbo, this will work if you have a turbo mounted further forward of the engine or somewhere else beside the standard location. There is a 3/8 NPT hole tapped into for whatever fitting/sensor you desire. Will only work for GTE!
Sold Individually, comes with 2 bolts and the O-ring for installation.
