Use a 3-inch Hybrid Racing Cold Air Intake on a compatible RSX, EP3 Civic Si, or 2001–2005 Civic K-swap arrangement.
The intake is sized around the space available in the DC5 chassis and the airflow needs of the specified larger throttle body and RBC/RRC manifold. It keeps the battery in its original position while moving the filter to a cooler air source. Hybrid Racing reports 5–10 hp, or up to roughly 10%, over a short-ram setup in its testing; results vary with the build and tune.
