Injen 08-13 Subaru WRX/STi 2.5L (t) Polished Cold Air Intake

If you're looking to get more out of your 2008-2013 Subaru Impreza WRX or STi, this Injen SP Series cold air intake is designed to help your engine breathe easier. This intake system replaces the restrictive factory airbox with a smooth, polished 6061-T6 aluminum tube, creating a more direct path for air to enter the engine. This improved airflow is key to unlocking extra horsepower and torque.

Injen has a long history with tuned intake systems, holding several patents on their tuning process. This SP intake utilizes their MegaRam (MR) Technology and Air Fusion, which work together to ensure that while airflow is increased, the air-fuel ratio remains safe for your engine. The kit includes a custom heat shield to help keep intake air cooler, and a serviceable SuperNano-Web dry air filter that offers good filtration without restricting airflow. You'll also notice a more aggressive, throaty engine tone when you step on the gas.

This kit is designed as a direct fit for your Impreza WRX or STi, meaning no additional tuning is required to see the performance improvements. It comes with everything needed for installation, including the tubing, filter, heat shield, and hardware.
