Intake Manifold

Features

The intake manifold is a branched pipe that takes in air and delivers it to each engine cylinder.Flow is optimized so that an equal allocation of fresh air mixes thoroughly with fuel for increased output and better fuel efficiency.

The Keihin Advantage

Downsized while retaining engine output
In order to create an intake manifold for direct-injection engines that is more compact while delivering better engine output and fuel efficiency, we have reconfigured the design so that the fuel supply location is in front of the cylinder head while maintaining pipe length and capacity.The unit is also reinforced in every way possible to make it strong and durable.

Stable air supply
Smooth airflow is the most essential function that an intake manifold performs. At Keihin, we run simulations that visually represent the fluid dynamics of the unit to decide its final shape.The result is a more stable and equally-distributed air supply to the engine resulting in a high responsiveness comparable to turbo-powered vehicles.
