    B&M Adjustable Vacuum Modulators let you adjust your shift points within a range of 2-4 mph. With a gold cadmium finish and an O-ring seal to stop leaks, they will look as good as they work. Note: If your engine does not make adequate vacuum you will not be able to make the stock or B&M modulator work properly usually resulting in late, hard shifts.
