Running a cooling system on a Model 3 drive unit project is now easier than ever. Thanks to TorqueMountain's coolant line adapters, you can easily use -16 AN lines on your build. Adapting to AN lines enables use of widely available AN standard--a racecar industry standard. Not only is it easier to use AN lines, but it results in a clean, professional, easy to service cooling system. TorqueMountain uses AN lines on their builds whenever possible. Price is per pair.
