Offenhauser C Series Intake Manifolds
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 Dual Port Intake Manifolds
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.

Offenhauser 360 Degree Single-Quad Dual-Port Intake Manifolds
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 Cast Aluminum Valve Covers
Offenhauser cast aluminum valve covers have one of the largest application offerings, to cover some of the rarest engines that many neglect to cover. They feature a stout cast aluminum design to resist those gasket-sealing woes, and the finned tops add style while dissipating engine heat. The covers have a high-luster polished finish, with the classic Offenhauser name to top them off.

Offenhauser 360 Degree Single-Quad High-Rise Intake Manifolds
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.
