Searching for a factory-style Ram Air or H.O. aluminum intake? Look no further, because OPGI has excellent reproductions of these hard-to-find manifolds. Cast aluminum manifolds are available for various 1969-72 Pontiac engines. Each intake features the correct casting number and "W" snowflake logo used by the Winters Foundry that produced the originals. With 1969-70 manifolds being correct for Ram Air IV 400 engines and 1971-72 manifolds being correct for H.O. 455 applications—all manifolds will work on 1965 and up 350-455 engines. Manifolds have machined mounting surfaces and all of the correct mounting holes for a pain-free installation.
