These Quick Fuel FOUR DOOR power valves feature an exclusive in-house design that has become the preference of professional race teams in virtually every circuit where carburetors are used. They have a greater flow capacity, a quicker response rate, and tighter limit bands that allow engine builders to precisely tune the power enrichment phase of their calibration. All Quick Fuel FOUR DOOR power valves are hand-tested and set to the stamped value. Their thicker molded diaphragm adds increased protection against backfire-induced rupture.
