The Injen SP polished short-ram intake for 2006–2009 Honda Civic Si replaces restrictive stock plumbing with 6061-T6 aluminum tubing and Injen’s MR and Air Fusion tuning. The kit includes a SuperNano-Web dry filter and necessary hardware, yields dyno-proven gains near 8.5 hp and 7 lb-ft of torque, maintains safe A/F ratios and adds an aggressive engine tone without requiring additional ECU tuning.
