The Cobb SF Air Box is a game - changer for your Subaru. It's designed to fit multiple Subaru models including the 2005 - 2009 Legacy GT, 2005 - 2009 Outback XT, 2008 - 2014 WRX, 2008 - 2014 STI, and 2009 - 2013 Forester XT. This air box combines the advantages of a cold air intake with the excellent performance of the SF Intake. The factory inlet smartly directs cold air from the front grill right into the SF Airbox, which wraps around the SF Intake. It keeps hot engine bay air out of the intake system, ensuring consistent intake performance and more horsepower. It also cleverly separates rainwater from the intake air, avoiding the water ingestion problems that often trouble in - fender cold air intakes. Constructed from 16 - gauge aluminum, it comes with a one - piece surround, a directional lid, stainless - steel hardware, and all the parts needed for an easy installation with an OEM - quality fit and finish. It features a wrinkle black finish and is equipped with stainless - steel hardware for durability. Installation is a breeze, and an installation guide is included.




Using the Cobb SF Air Box is easy. First, make sure your vehicle's engine is cool before starting the installation. Refer to the included installation guide for step - by - step instructions. Once installed, your air box will start directing cold air to the intake, improving your engine's performance. As for maintenance, it's a good idea to check the air box regularly for any signs of dirt or debris. You can use a soft brush to gently clean the exterior. If you live in a very dusty area, you may need to clean it more often. Also, keep an eye on the stainless - steel hardware to make sure it doesn't rust. If you notice any damage to the aluminum construction, it's best to have it inspected or replaced. Remember, proper use and maintenance will ensure your Cobb SF Air Box lasts a long time and keeps your Subaru running smoothly.
