The NorthWest K-Series Intake Manifold (RBC Style) is designed for Honda K-Series performance builds, offering improved airflow characteristics over factory intake manifolds while maintaining strong mid-range performance.

Designed for both naturally aspirated and turbocharged applications, this manifold features an enlarged plenum and optimized runner design to improve airflow efficiency throughout the RPM range. The design focuses on increasing airflow potential while maintaining the drivability and response that make K-Series engines popular.

Manufactured from high-quality cast aluminium, the NorthWest K-Series Intake Manifold is built for durability and performance use. The thicker cast construction also allows room for further port matching and modification for higher-power applications.

The angled runner design helps provide improved hood clearance across a wide range of K-Series engine combinations, while the 72mm throttle body opening supports OEM throttle bodies and can be port matched up to 76mm for larger aftermarket throttle bodies.
