• 100% quality assurance tested, more responsive, less expensive, easier to install.
• Improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.
• The new, cast-aluminum Intake Manifolds for Honda's K-series engines are a direct-fit replacement for all '06-'11 Civic Si engines thanks to their unique design and throttle body flanges, which are compatible with OEM throttle bodies as well as those as large as 76mm.
• The design incorporates runners that are similar in length to the RBC's but with larger bores, a special tapered design, as well as a larger, tapered plenum that together preserve mid-range power but increase and accelerate airflow to allow for significant top-end power gains.
