DEFROSTER/HEATER BOOSTER SYSTEM FOR ALL BEETLES AND KARMANN GHIAS A great way to effectively increase the airflow to your defroster Booster system includes 2 fans that mount in the ductwork and are approx. 3 times more powerful than conventional booster-type kits. These fans eliminate the need to rely on engine RPM for blower output. A 4-position, 3-speed switch (low, medium and full) puts you in complete control of fans' output. In addition to this increased airflow, the patented method of drawing heater return air from the vehicle's interior significantly raises the temperature level. Another benefit of this system is the elimination of engine compartment fumes and road dust from the heater supply. Kit includes all necessary components, hardware, wiring and instructions. For all Beetles and Karmann Ghias.
