Rotrex superchargers utilize a unique traction drive system that sets it apart from other centrifugal-style superchargers. For best performance, Rotrex recommends replacing this fluid every 50,000 miles. This bottle of traction fluid is plenty enough for one supercharger service (typically 750ml).

Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.
