Honda B16/B18C PR3/P73 Billet Intake Manifold
Description
The factory cast intake systems often fall short when demanding maximum performance at high RPMs or under intense boost. Our innovative plenum engineering ensures a 100% equal airflow distribution to every single intake port of the 4-cylinder B-Series engine. This flawless flow dynamics guarantee safe, balanced power delivery across the entire powerband, preventing dangerous lean conditions and maximizing horsepower.
To support your upgraded fueling demands, this manifold comes complete with a custom-matched, high-flow billet fuel rail designed for your primary injectors. To match your specific airflow requirements, the manifold accommodates multiple throttle configurations, offering dedicated flange choices for 60mm, 70mm, or massive 75mm throttle body setups.
-
- High-Velocity Plenum Design: Engineered with a high-capacity plenum optimized for instant throttle response, uniform air distribution, and absolute structural strength under immense boost.
- Velocity Stack Design: Individual runners featuring high-flow venturi effect velocity stacks for superior cylinder filling and optimized high-RPM air velocity.
- Auxiliary Injection Ready: Built-in provisioning to support up to 4 ports of water-methanol or nitrous injection (1 dedicated port per cylinder).
