Does this intake require an ECU reflash?

While the COBB SF Intake + Airbox is designed to fit and function with the factory ECU, an ECU reflash is recommended to optimize performance and take full advantage of the improved airflow. Without a reflash, you may not see the full potential gains.

What is included with the COBB SF Intake + Airbox?

The COBB SF Intake + Airbox includes the airbox, intake tubing, and necessary hardware for installation. Please refer to the manufacturer's instructions for a complete list of included components.

How does this intake affect engine sound?

Product Details

If you're looking to get more out of your 2008-2014 Subaru Impreza's engine, the COBB SF Intake + Airbox is a solid choice. This system is designed to replace the restrictive factory airbox and intake tubing, allowing your engine to breathe more freely. By improving airflow, you can expect a more responsive throttle and a subtle improvement in engine sound under acceleration. This is a popular upgrade for Subaru owners who want to enhance their vehicle's performance and driving experience.

The COBB SF Intake + Airbox is built with durability and performance in mind. It features a well-built airbox that helps to isolate the intake air from engine bay heat, ensuring cooler air enters the engine. Cooler air is denser, which means more oxygen is available for combustion, leading to better power output. The intake tubing is shaped to promote smooth airflow, reducing turbulence and restriction. This combination helps the engine perform more efficiently. Installation is designed to be straightforward, replacing the stock components with minimal fuss.

When installing the COBB SF Intake + Airbox, it's important to ensure all connections are sealed properly to prevent unmetered air from entering the system, which could affect engine performance and check engine lights. This intake is designed to work with the factory ECU, but for optimal results and to take full advantage of the improved airflow, many Subaru owners choose to pair it with an ECU reflash. This ensures the engine's computer is calibrated to take advantage of the new intake's capabilities.
