SP Short Ram Air Intake System

The Injen SP Short Ram Air Intake System (SP1577BLK) is engineered for the 2006-2011 Honda Civic Si with the L4-2.0L engine. This intake boasts "Dyno Proven Gains" of up to 8.5 HP and 7 lb-ft of torque, providing a noticeable power increase. The "Short Ram Air Intake Design" contributes to enhanced engine breathing. According to product information, this system does not require a tune for installation and maintains safe A/F ratios. Installation is described as straightforward and a "bolt-on installation." While some sources indicate "no tune required," one user reported experiencing a "lean condition" and "check engine light" after installation on a non-Si model, highlighting the importance of proper installation and potentially monitoring air-fuel ratios, especially if modifications are made beyond just the intake. This intake is specifically designed for the 2006-2011 Honda Civic Si, including both FA5 Sedan and FG2 Coupe models equipped with the L4-2.0L K20Z3 engine, compatible with the 8th-generation Honda Civic Si.
