The AVP MAX A/C Mod Stage 1 is engineered for F-Series Ford trucks from 1994 to 2008 (plus 94-96 Bronco & 00-05 Excursion) that need truly cold air conditioning performance. From the factory, engine coolant constantly flows through the heater core—even during A/C operation—causing the heater core to radiate heat in the HVAC box and compromising cold air delivery. This mod solves that problem by automatically shutting off coolant flow to the heater core when you select MAX A/C, blocking unwanted heat from entering your A/C vents.
Users typically see duct temperatures drop by 10°F or more, making summer driving far more bearable. Installation is straightforward (about 15 minutes) and requires no special tools; everything needed is included, with easy-to-follow instructions. The kit works for all trucks in this year range, whether diesel or gas powered.
Even vehicles with some factory valves benefit because many OE units don’t shut off fully—this upgrade removes that limitation. Enjoy true cold air A/C every time you hit MAX.
