This Cobb SF Airbox is a must - have for your 2002 - 2007 Subaru WRX, 2004 - 2007 Subaru STI, or 2004 - 2008 Subaru Forester XT. It's built with 16 - gauge aluminum, featuring a wrinkle black finish. It uses the factory snorkel to bring in cold air, and all hardware is made of stainless steel. It offers an OEM - quality fit and is super easy to install, complete with an installation guide. This airbox combines the advantages of a cold air intake with the great performance of the SF Intake. The factory inlet channels cold air from the front grill into the airbox, which houses the SF Intake. It keeps hot engine bay air out, preventing horsepower loss. Also, it separates rainwater from the intake air, avoiding water ingestion problems common in in - fender cold air intakes.
Using this Cobb SF Airbox is simple. First, follow the included installation guide to fit it properly in your Subaru WRX, STI, or Forester XT. The factory snorkel will do its job of bringing in cold air, so make sure it's connected well. When driving, the airbox will keep hot engine air out and separate rainwater. For maintenance, check the airbox regularly for any signs of damage or debris. Clean it gently with a soft cloth and mild cleaner if needed. Avoid using harsh chemicals as they might damage the wrinkle black finish. If you notice any issues with the stainless - steel hardware, like rust or looseness, replace or tighten them right away. With proper use and care, this airbox will serve you well for a long time.
