Product Description

The Injen SP1577BLK Black SP Short Ram Intake is a direct-bolt-on performance intake system engineered specifically for 2006-2011 Honda Civic Si models equipped with the 2.0 L naturally aspirated engine. This SP Series intake replaces the restrictive factory airbox and intake tube with mandrel-bent 6061-T6 aluminum tubing and incorporates Injen's patented MegaRam (MR) and Air Fusion technologies to optimize airflow while maintaining safe air-fuel ratios without requiring additional ECU tuning. The fully serviceable SuperNano-Web dry air filter increases filter surface area for better airflow and easier maintenance. 

Dyno testing shows gains of up to approximately 9 hp and 7 lb-ft of torque compared to the stock intake, delivering improved throttle response and a noticeable performance boost. The short ram design also produces an aggressive induction sound under acceleration, adding to the driving experience. Crafted from durable 6061-T6 aluminum and finished in sleek black, this intake system enhances both performance and under-hood aesthetics. Backed by Injen's limited lifetime warranty and carrying CARB Executive Order D-476-8 for emissions legality where accepted, the SP1577BLK is a reliable upgrade for Civic Si owners seeking enhanced airflow and power.
