Our selection of 1974 Volkswagen Thing Heating Components includes heater boxes, j-tubes, heater hose, and installation hardware.

Replacing your VW Heater Box will allow you to use the defroster and cabin heater without compromising your engine's horsepower output.

Our VW J-Tubes can be installed to replace the heater box. This will lighten the weight of your exhaust and allow for more performance exhaust options. However, they eliminate the defroster and cabin heater in your 1974 VW Thing.
