Flanged Performance 1-1/2" Heater Box, Left, Made in Denmark

These European made Performance Heater Boxes are made from larger 1-1/2" diameter tubing, adding additional exhaust flow for your performance engine application, yet still providing heat.  The heat output is not as good as a stock heater box, but is more than adequate to help keep you warml on a cold day.  These boxes are designed to fit our #7320 and #55-7320 flanged headers.  You can also weld a flange on the header of your choice.
