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.

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 Equa-Flow Dual-Quad Low-Rise intake manifolds make good use of Offy's 360 degree technology to feed all cylinders evenly and make more power. This results from their single-plane configuration, with its unique split-plenum chamber and tuned intake runners. That combination delivers the fuel-air charge evenly to all cylinders for more power without flat spots. Edebrock Performer series and Carter AFB carburetors are recommended. Some applications cannot mount Holleys in any manner, or clear HEI.

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.

Offenhauser 360 degree Equa-Flow Single-Quad high-rise intake manifolds feature a design for full-capacity operation. This combination of unrestricted fuel-air flow and a divided plenum means no flat spots throughout the entire rpm range. What does all this mean? The equal fuel flow to each cylinder increases horsepower and torque, while evening-out individual cylinder temperatures. Power bands start as low as 1,800 rpm with a small carb and climb all the way to 8,800 rpm with a big one.

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.

Offenhauser's Super Sonic intake manifolds are a refinement of their popular Port-O-Sonic intakes. They're designed specifically to take maximum advantage of the Holley 4500 on the track or strip. The big plenum and hefty runners work well together. However, the real gains come from four "paravanes" located at the bottom of the plenum, which direct the fuel/air charge for even distribution with minimum turbulence. The result is a power band that stretches from 3,400 rpm to 8,800 rpm. Super Sonic manifolds are available in a variety of configurations for different cylinder head and carburetor applications.

High-rise tandem 4-barrel setups have said "power" for years. Offenhauser single-plane 360 degree Equa-Flow Dual-Quadrajet high-rise intake manifolds deliver that power by placing each carburetor above one of the unique split plenums that they pioneered. Their 360 degree design means that the fuel-air charge is rammed down short runners to all cylinders continuously, producing a fatter power curve with no flat spots. Some applications will not accommodate large HEI-style distributor caps. Order the model recommended for your vehicle, engine, and carburetor setup.
