How to Install NSX Stanceparts Air Cup Kit (Full DIY)

This video is a long detailed video meant to walk you through a step by step installation of the Stanceparts cup kit on a 91-05 Acura/Honda NSX. This is using Stanceparts cups with a 1.5Gal Viair tank/compressor combo. Modifications I've added to the factory setup are: Electronic Purge Valve and switched compressor and purge valve. This is for a 2 cup setup and front mounted tank, however it will work the same with the tank mounted in the trunk, you will just have to use longer wires and possibly thicker gauge wires due to the added length.
