Weiand Hi-Ram Tunnel Ram Intake Manifolds are created for drag racing, truck/tractor pulls, and performance marine applications where high rpm is required but bottom-end torque isn't. They mount either single or dual square-mount carbs and, depending on the application, have power bands that run from 2,500 rpm to as high as 9,000 rpm. Stock electronic ignition will NOT clear.

Weiand is a powerhouse in the high-performance industry that offers top-quality intakes and superchargers. Established in the 1930s, the company is responsible for engineering the first aluminum intake manifold on the market AKA the High Weiand manifold. Later on in 1949, Weiand would change the game with a number of "tri-power" and four 2-barrel manifolds. After World War II, Weiand manufactured a range of aluminum cylinder heads for flathead Ford engines. During the 1950s and 60s, their engineers would provide a plethora of innovative advancements such as the first dual plane, 180-degree intake as well as their outstanding Hi-Ram manifold with the exclusive D-port technology.

In the 90s, Weiand would be regarded as the first OE supplier of superchargers to Mercury Performance Marine. They would also design their exceptional Stealth series dual plane manifolds, their Pro-Street supercharger would be emissions legal certified by CARB, and the company would be granted the industry's first "E.O." for an intake manifold. Later on, Weiand released their 8-71 supercharger for the Small Block and Big Block Chevy and they follow up with the first aluminum LS-1 intake manifold in 2002.

Fast forward to modern times and Weiand is well-represented by their superior parts and accessories that bestow superior horsepower and torque gains. Get more air into your engine and unlock its full potential by integrating the inimitable power-building components by Weiand.
