This Cobb SF intake and air box combo is a top - notch upgrade for your 2008 - 2014 Subaru STI, 2008 - 2014 Subaru WRX, or 2009 - 2013 Subaru Forester XT. It combines the best of short ram and cold air intakes without the drawbacks. The composite intake body rejects heat effectively, and the 4 - ply steel - reinforced silicone post - MAF ensures durability. The 16 - gauge aluminum airbox and pre - oiled, cleanable, reusable custom filter element are great features. It uses the factory snorkel for a cold air feed, and installation is a breeze with an included guide. This intake system is designed to maintain optimal airflow and minimize turbulence, thanks to a CFD - designed velocity stack and an air flow straightener grid. It eliminates dead spots caused by turbulence in other aftermarket intakes. Made from high - temperature plastic composite, it saves weight and keeps intake air cooler. The SF Air Box adds cold - air intake benefits and prevents hot engine bay air from entering. It also separates rainwater from the intake air. All 08+ Subaru aftermarket intakes need tuning, and COBB Tuning provides Off - The - Shelf Maps for the Accessport. Note: The COBB Tuning SF Intake system for the 2008+ WRX requires specific OTS mapping from the AccessPORT ecu tuning device. California Prop 65 Warning: Operating, servicing, and maintaining your vehicle can expose you to harmful chemicals.

Using this Cobb SF intake and air box is quite straightforward. First, refer to the included installation guide for a smooth setup. Once installed, it will start enhancing your vehicle's performance right away. When it comes to tuning, you'll need to use the specific Off - The - Shelf (OTS) mapping provided with the AccessPORT ecu tuning device, especially if you have a 2008+ WRX. This ensures the MAF sensor reads correctly and your engine runs within safe parameters. As for maintenance, the custom filter element is pre - oiled, cleanable, and reusable. You can clean it periodically to keep the intake system working at its best. When servicing your vehicle, always do it in a well - ventilated area to avoid breathing in harmful chemicals like engine exhaust. And remember, don't idle the engine more than necessary. If you have any questions about the OTS mapping or the installation, don't hesitate to give us a call.
