Perrin presents its redesigned V2 cold air intake system for the 2002 - 2007 Subaru WRX and 2004 - 2007 Subaru STI. It's available in powder - coated wrinkle red or wrinkle black finish. The open - cell foam element effectively captures dust and dirt. The CNC mandrel bent aluminum tubing ensures smooth airflow. When you step on the throttle, you'll enjoy a throaty, deep tone. It can potentially gain an estimated 10WHP without the need for tuning. With intermediate installation effort, an installation guide is provided. It comes with a 5 - year manufacturer warranty. Inside the box, you'll find a PERRIN MAF adapter, a cold air extension, a foam air filter, two silicone couplers, all necessary installation hardware, a license plate frame, instructions, stickers, and a warranty. Perrin's research relocated the intake filter to the fender well for optimal airflow, resulting in more consistent sensor temperatures, better dyno tuning runs, and smoother power delivery.
Using your Perrin cold air intake system is straightforward. First, follow the included installation guide carefully. It's an intermediate - level installation, so take your time. After installation, you can enjoy the improved power and the great throttle sound. As for maintenance, regularly check the open - cell foam air filter. If it's dirty with dust and dirt, clean it according to the instructions. The powder - coated finish is durable, but try to avoid scratches. Remember, this system doesn't require tuning, so don't mess with the engine settings. If you have any issues, refer to the 5 - year manufacturer warranty.
