Revshift's intake manifold designs take advantage of high air-flow characteristics, inertial effects, and pressure-wave tuning to achieve air density in cylinders that substantially exceeds the oem intake manifold.

These manifolds are fabricated from high quality 6061 aluminum. They are 100% precision TIG welded by a skilled professional for maximum strength and durability. All flanges are CNC cut to perfection from thick 6061 aluminum. Although it is not necessary in naturally aspirated applications, air/fuel tuning is recommended to maximize horsepower gains and reliability.
