Offenhauser is one of the greatest names in racing history. Offenhauser speed equipment earned its reputation on the Grand Prix racing circuit during the 1930's and 1940's. Today, you can achieve the same power and performance with an Offy intake, flathead Ford cylinder head or transmission adapter. All Offenhauser intake manifolds are cast from high grade aluminum alloy and are precision machined to equalize fuel distribution to all cylinders for more power.
