Injen 06-09 Civic Si 2.0L 4Cyl. Coupe & Sedan Black Short Ram Intake

If you're looking to get more air into your 2006-2011 Honda Civic Si, this Injen SP Short Ram Intake is a solid choice. It's designed to let your engine breathe more freely, which can make a real difference in how the car performs, especially when you're pushing it hard.

The intake tube is made from 6061-T6 aluminum, which gives air a smooth path without a lot of restrictions. Injen uses their patented MR Technology and Air Fusion process, which they say helps tune the intake for safe air-fuel ratios and better performance. This means you get a noticeable increase in horsepower and torque, with dyno tests showing gains of up to 8.5 hp and 7 ft-lbs of torque. It also comes with a serviceable SuperNano-Web dry air filter that offers good filtration and can be cleaned and reused. You'll also notice a more aggressive engine tone when you step on the gas.

This kit includes everything you need for installation, including the tubing, filter, and hardware. It's designed as a direct fit, so you shouldn't need any extra tuning to get the benefits. Injen backs this intake with a limited lifetime warranty.
