Grille mounted air ducts are arguably one of the most effective means of shoving dense, cool air into an engine, and for racers on the NASCAR and drag racing circuit in the mid ‘60s, the easiest route to ram air was to swap a headlight for a hand-fabricated scoop ducting air straight to the carburetor. Now you can use the same technology on your muscle car with new bolt-in Headlight Air Scoops and Screens from Spectre Performance, available for many muscle car applications. Round scoops replace any standard 5.75-inch round headlight with a 6061-T6 aircraft grade spun aluminum funnel perfect for permanently swapping out the high beams for air ducts on quad-headlight cars- and they include an adapter to allow direct installation with a factory headlight bezel. Square injection molded urethane scoops are also available for late 1970s through mid-‘90s muscle cars with square quad headlights. Designed for use with Spectre’s four-inch Profab Muscle Car Cold Air Intake Kits, the funnels can be combined with several different air ducts and air box packages to create a unique, stylish, and functional system that will dramatically drop air inlet temperatures and in turn increase overall horsepower. Testing has shown that every 10-degree reduction in incoming air temperature is worth a 1.5 – 2.0% gain in both torque and horsepower. Considering underhood temperatures can run well over 200 degrees in a classic muscle car, dropping incoming air to ambient temperature can yield a sizable double-digit power increase. Spectre Performance offers a full range of high performance air filters, cold air intakes and automotive accessories engineered and tested in the most extreme conditions on earth for maximum performance, durability and style.
