Do you have a Holley Hi-Ram intake manifold on your project car that is in need of a wide-open-throttle switch? NOS have developed a very nice, 6061 aluminum, black anodized, switch bracket that will look right at home on that Holley Hi-Ram manifold. Installs in minutes underneath the existing throttle cable bracket and utilizes slotted mounting holes for adjusting the switch engagement. Wide-open-throttle switches are essential when using a stand-alone nitrous system, or if needing to switch a device, such as air conditioner compressor or alternator field winding, based on wide-open-throttle. Built from sturdy, black anodized, 10 gauge (0.134"), 6061-T6 aluminum for good looks and dependability.
