The Injen SP cold air intake for 2001–2005 Honda Civic (DX/LX/EX 1.7L) replaces restrictive stock plumbing with 6061-T6 aluminum tubing and Injen’s patented MR and Air Fusion tuning. It includes a SuperNano-Web dry filter, converts to a short-ram layout and delivers dyno-proven gains around 5 hp and 6.7 lb-ft of torque while maintaining safe air–fuel ratios and providing an aggressive intake tone.
