The Injen SP cold air intake for 2006–2009 Honda Civic EX 1.8L (manual) replaces restrictive stock plumbing with smooth 6061-T6 aluminum tubing and patents like MegaRam for tuned gains. The kit includes a SuperNano-Web dry filter and hardware, delivers dyno-proven gains up to about 8 hp and 6.2 lb-ft of torque, maintains safe air–fuel ratios and produces an aggressive intake tone without requiring additional tuning.
