Injen 06-09 S2000 2.2L 4Cyl. Polished Cold Air Intake

If you're looking to get more sound and power out of your 2006-2009 Honda S2000, this Injen RD Series cold air intake is a solid choice. It's designed to pull cooler, denser air from behind the front bumper, which helps your engine breathe better and make more power. You'll notice a more aggressive engine tone when you step on the gas, and Injen backs it with a limited lifetime warranty.

The heart of this system is the smooth, mandrel-bent aluminum tubing. This construction means there are no restrictions in the pipe, allowing air to flow freely into the engine. It comes with a serviceable Injen SuperNano-Web dry air filter that offers a good balance of airflow and filtration. Injen's testing shows gains of up to 11 horsepower and 15 lb-ft of torque, and they've made sure the air-fuel ratios stay safe without needing a tune.

This intake is finished in a polished aluminum look, which really stands out in the engine bay. It's a direct bolt-on installation, meaning you won't need any welding or major modifications. Just be aware that the CARB EO number D-476-5 is only valid for the 2006-2007 models.
