PRODUCTSIntake Manifolds

Products Image

Intake Manifolds (or, Inmani in Japanese-English) are designed to channel air or air/fuel mixtures into each cylinder in a vehicle's engine.
The design of an Intake Manifold is based on creating channels, or pipes, leading to the cylinders. The Intake Manifold also includes a chamber, which is designed to reduce the amount of noise created by the intake of air. Also, the amount of air is controlled carefully by the funnels to direct the ideal air/fuel mixture into the cylinder and ensure optimal engine output.
At ROKI AMERICA, we are able to design a superior and highly efficient Intake Manifold while adhering to the layout space provided by the car-maker.
