Phil Weiand founded the Weiand Company in the 1930s as a performance parts warehouse, selling a variety of speed parts. In 1937, the "High Weiand" manifold was manufactured and marketed as the first Weiand product. It was the market's first aluminum intake. Weiand debuted a line of aluminum cylinder heads for flathead Ford engines shortly after WWII, introducing a series of "tri-power" and four 2-barrel manifolds in 1949.

In 1952, Weiand introduced the famous "Drag Star" line of "log" manifolds for Hemi engines, and in 1957, Weiand developed complete blower drives for the GMC 6-71 supercharger. Weiand introduced the first dual plane, 180o intake, known as the "Colt," in 1965, and the "Hi-Ram Manifold" and its patented D-port technology in 1968. Weiand introduced the popular "X-terminator" single plane manifold series in 1972, and high-performance aluminum water pumps the following year. In 1974, the "X-CELerator" series of high-performance single plane intakes was developed. In 1978, the first models of the well-known "Team G" series of 360o racing manifolds were introduced.

Weiand's "Action" series of high-performance replacement manifolds debuted a year later. In 1990, Weiand became Mercury Performance Marine's first OE supplier of superchargers, and over the next three years, the "Stealth" series of high-performance dual plane manifolds were designed, the "Pro-Street" supercharger was certified "emissions legal" by CARB, and Weiand received the industry's first "E.O." for an intake manifold.

Weiand created the 8-71 supercharger for small-block and big-block Chevys in 1996, and the first aluminum LS-1 intake manifold was released in 2002. On its newest intakes, the Warrior line, Weiand began designing manifolds in 2005, using Computational Fluid Dynamics software to deliver perfectly designed runner lengths for maximum air/fuel delivery. More air means more power in your engine.
