Skunk2 Pro Series 06-10 Honda Civic Si (K20Z3) Intake Manifold (Race Only)

This item cannot be shipped to California due to Carb regulation with CA. Skunk2s engineers went back to the drawing board when they set out to improve the already popular 06-11 Civic Si’s RBC intake manifold. Each of Skunk2’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. Skunk2’s all-new, cast-aluminum Pro Series Intake Manifolds for Honda’s K-series engines are a direct-fit replacement for all 06-11 Civi
