The creation of the all-new SP-Series system for your Civic Si was inspired by the strong racing heritage that stands behind this legendary brand. The new intake is an application-specific system, engineered to remove the restrictions on the way of the airflow to your engine and maximize the power gains. As per the manufacturer, you’ll get faster acceleration and much better fuel economy at cruising speeds.

The installation process is easy, as this is a bolt-on upgrade that requires no drilling or cutting to be attached properly. The SP Series Intakes are pretty compact and will easily install under the hood of your Civic Si.
