Product Description

The Injen SP1476P Polished SP Short Ram Intake is a performance-focused air intake system engineered for direct fitment on 2002-2006 Acura RSX Type S and 2002-2005 Honda Civic Si models equipped with the 2.0 L inline-4 engine. Part of Injen's SP Series, this intake uses mandrel-bent 6061-T6 aluminum tubing and patented MegaRam (MR) and Air Fusion technologies to improve airflow over the restrictive factory air path while maintaining safe air-fuel ratios without the need for ECU retuning. The included SuperNano-Web dry air filter enhances filtration and airflow, and it's fully serviceable for long-term maintenance.

Dyno testing shows gains of up to approximately 12 hp and 9 lb-ft of torque compared to stock intake designs, resulting in improved throttle response and a more engaging driving experience. The polished aluminum finish adds a refined look to your engine bay, while the aggressive induction sound under throttle complements the performance upgrade. This intake is backed by Injen's limited lifetime warranty and features CARB Executive Order D-476-5, indicating emissions compliance where this EO is accepted.
