Offenhauser Dual Port Intake Oldsmobile 400 425 455 Olds 88 442 Cutlass Rocket

Manufacturer: Oldsmobile

The offenhauser 360 Degree Equa-Flow High-Rise intake manifolds feature a 360 degree design for full-capacity operation. This is the rare dual port version, which is designed to increase fuel mileage, because the intake ports are a split port design, as the fuel and air from primaries are totally separated from the fuel and air from the secondaries.
