Honda K-Series Billet Intake Manifold – Best Ultimate Side Feed Twin Injector Performance Upgrade for K20

Honda K-Series Billet Intake Manifold

 

Honda K-Series Billet Intake Manifold by Velocity Race is engineered for enthusiasts seeking exceptional airflow, faster throttle response, and maximum performance from Honda K-Series engines. Designed specifically for Honda K20 engines without a water passage, this premium intake manifold is precision CNC-machined from high-grade T6061 billet aluminium to provide outstanding strength, durability, and accurate fitment.

 

The Honda K-Series Billet Intake Manifold features a high-volume side-feed plenum with an optimized runner design to improve airflow distribution and volumetric efficiency. Compared to the factory intake manifold, the larger plenum allows the engine to breathe more efficiently throughout the RPM range, resulting in improved throttle response, stronger mid-range torque, and increased top-end power.

 

Built with a twin injector configuration, this intake manifold is ideal for naturally aspirated and turbocharged engines requiring additional fuel delivery. Whether you’re building a high-compression race engine, a turbocharged street car, or a dedicated drag or circuit vehicle, the Honda K-Series Billet Intake Manifold provides the airflow capacity and fuel system flexibility required for demanding performance applications.

 

Manufactured using advanced CNC machining technology, every Velocity Race intake manifold is carefully inspected to ensure excellent machining quality, accurate fitment, and long-term reliability. Trusted by workshops, racers, and Honda enthusiasts worldwide, this intake manifold delivers the motorsport-quality performance expected from Velocity Race products.
