The AQ Motorsports Cold-Air Intake for the 2008 WRX and STI was designed to improve horsepower, torque, and response without affecting fuel trims and tuning.

On our Mustang dyno, a bone stock 2008 STI gained 12whp and 4lb/ft of torque peak with consistant gains of 12-15tq through the powerband. Peak torque also arrives sooner for faster response.

The gains in power come from reduced restriction. Pulling cool air from the passenger fenderwell, the factory inlet scoop can be retained to provide more cool fresh air to the unit.

Features:
- Mandrel bent aluminum construction
- CNC machined MAF bracket
- TIG welding
- AEM Dryflow Filter w/ Integrated Velocity Stack (uses no oil!)
- High Quality Silicone Couplers and Clamps
- Fits with factory intake scoop
- Includes brackets that firmly mount the intake and minimize vibration
- Available in Harman Signature Polished Finish or Black Crinkle Coat for great looks

No Tuning Required:

The AQ Motorsports Cold-Air intake can be used on vehicles with stock ECU, off the shelf tunes (such as Cobb), or custom tuning. It will not throw an Check Engine lights or cause issues with idle, driveability, or air-fuel ratios.
