BMC 2009 Ford Focus II 2.5 T RS Oval Trumpet Airbox Kit

This is the BMC Oval Trumpet Airbox Kit, specifically made for the 2009 Ford Focus II with the 2.5 T RS engine. This kit replaces your stock airbox to help your engine breathe more freely. By allowing more air into the engine, it can lead to a more responsive feel and potentially improved performance.

BMC is known for well-built intake systems, and this airbox is no exception. It features an oval trumpet design, which is intended to help smooth the airflow entering the engine. The construction is solid, aiming to provide a durable component that can handle the heat and vibration under the hood. Installing this kit is a direct replacement for your factory airbox, making it a straightforward upgrade if you're looking to enhance your Focus RS's intake system.

Keep in mind that this airbox kit is not CARB approved, meaning it cannot be legally shipped to California. Always refer to your local emissions regulations before installing aftermarket parts.
