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

HONDA K-SERIES BILLET INTAKE MANIFOLD

 

The Honda K-Series Billet Intake Manifold by Velocity Race is engineered to maximize airflow, horsepower, and throttle response for serious Honda enthusiasts. Designed specifically for Honda K20 and Honda K24 engines without a water passage, this Honda K-Series Billet Intake Manifold features a high-flow center feed plenum, a 100mm throttle body opening, and precision CNC-machined runners to deliver exceptional airflow distribution and outstanding high-RPM performance.

 

Manufactured from premium T6061 billet aluminium, the Honda K-Series Billet Intake Manifold offers superior strength, lightweight construction, and excellent durability. The center feed configuration allows air to enter directly into the plenum, providing balanced airflow to every cylinder while improving volumetric efficiency, throttle response, and horsepower throughout the RPM range.

 

Unlike conventional cast intake manifolds, the Honda K-Series Billet Intake Manifold is CNC machined for maximum precision and consistent performance. This center feed design supports twin injector fuel rail systems and includes a 100mm throttle body adapter, allowing builders to install their preferred throttle body while maintaining unrestricted airflow.

 

Whether you’re building a naturally aspirated K20, a turbocharged K24, or a dedicated race engine, the Honda K-Series Billet Intake Manifold provides the airflow capacity, reliability, and performance required for street performance, drag racing, circuit racing, and time attack applications.

 

Every Honda K-Series Billet Intake Manifold is designed using advanced CAD engineering and manufactured with strict quality control to ensure accurate fitment, excellent durability, and motorsport-grade performance.
