Offenhauser Dual Port intake manifolds feature completely separate runner systems for the primaries and secondaries for more power across the rpm range. At low-load, the primaries feed the air/fuel charge through the smaller bottom passages at near sonic speed, improving power and efficiency. When the secondaries open, their charge goes through the bigger, cooler upper passages. Then, in turn, it is rammed into the cylinders when it encounters the high-velocity mix from the primaries. The results are better fuel economy and a 15-30 percent power increase across the entire rpm range. These manifolds are available in a variety of styles and options for many year/make and engine applications.

Add some muscle! Offenhauser C Series intake manifolds fill the gap between stock and competition setups for 4 and 6-cylinder cars and pickups. They improve torque in the mid and upper ranges, with power bands that span from 2,500 rpm to more than 7,000 rpm. Smaller applications use Holley 5200 or Weber 32/36 Series 2-barrel carbs. Holley 2300s can be used for competition with an adapter. Six-cylinder, 4-barrel versions can use square bore Holley or Carter carbs. Emission-control provisions can be blocked off for competition.

Offenhauser 360 degree dual-port single-quad intake manifolds feature completely separate runner systems for the primaries and secondaries. At low-load, the primaries feed the fuel-air charge through the smaller bottom passages at near sonic speed, improving power and efficiency. When the secondaries open, their charge goes through the bigger, cooler upper passages. Then, in turn, it is rammed into the cylinders when it encounters the high-velocity mix from the primaries. The result is better fuel economy, lower emissions, and a substantial power increase across the whole rpm range.

Offenhauser's dual quad high-rise manifolds take the best of the company's 360 degree Equa-Flow technology and double it. Each 4-barrel sits on top of its own split plenum, which feeds straight, tapered runners that dive directly from the plenum to the intake ports. This results in extremely even, efficient cylinder filling, which eliminates flat spots and produces hefty power bands, starting as low as 1,800 rpm and running as high as 8,800 rpm. Edelbrock Performer series and Carter AFB carburetors are recommended. Some applications cannot mount Holleys in any manner.
