D Series Pro Series Intake Manifold For Honda D15 D16 Civic Si CRX EG EK Del Sol

 

Our cast aluminum Intake Manifold for Honda’s D-series engines are a direct-fit replacement for most D-series engines and are compatible with all factory sensors. Our Intake Manifolds offer horsepower and torque gains greater than competitors’ manifolds but without compromising mid-range power output. The design incorporates specially tapered runners 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. Intake Manifold runner exits is also machined to best match the cylinder head’s ports. Our Intake Manifold’s shape and design also increases wave scavenging effects at the engine’s ideal operating range, which allow for a broad increase in usable power.
