Acura Rsx Racing Intake Manifold K20 K20A2 K20A3 K20z1 Base Type S Rsx-S

Pro Series Intake Manifolds for Honda's K-series engines feature larger plenums and shorter, oversized runners when compared to the RBC, and are cast with thicker wall material, leaving room for further porting for high-horsepower applications. Instead of producing a manifold with a significantly oversized plenum and excessively short runners that would sacrifice mid-range power, Pro Series manifolds were designed for the "street enthusiast" who wants more power but doesn't want to sacrifice mid-range performance to get it. The results are improved airflow, an enhanced venturi effect, and both mid-range and top-end power gains.
