Injen SP Series Cold Air Intake - Polished - Select 2005-2007 Subaru Impreza (2.5L) - SP1222P

Fits select 2005-2007 Subaru Impreza models, including 2.5i, Outback Sport, RS, WRX, and STI (2.5L).

Optimize your Subaru’s performance with the Injen SP Series Cold Air Intake. This flagship system replaces the restrictive factory airbox with mandrel-bent 6061-T6 aluminum tubing, providing a smooth, high-velocity path for airflow. By drawing cooler, denser air from outside the engine bay, the SP1222P delivers dyno-proven gains of up to 14 hp and 13 lb-ft of torque while maintaining a more aggressive, throaty engine note under full throttle.

The SP series features Injen’s patented MegaRam (MR) Technology and Air Fusion tuning processes. These innovations allow the intake to be precisely tuned to provide safe air-fuel (A/F) ratios across the entire power band without the need for additional ECU recalibration. This system includes a fully serviceable SuperNano-Web dry air filter, which offers increased surface area for high-volume flow and superior filtration. Manufactured in Pomona, California, this kit is CARB-exempt and includes all necessary hardware for a secure installation on factory mounting points.
