Calculator CFM Calculator

Offenhauser Dual Port 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 results are better fuel economy and a 15-30 percent power increase across the whole rpm range.

This intake is very popular in my country as well and I am lucky to be able to experience the big performance gain after the install. I know how my jeep perform without it and how aggressive it becomes after using this Offy intake.
