Show original supplier description
The Mishimoto Performance Air Intake is engineered to provide a significant airflow improvement for the Subaru Impreza WRX & STI GD/GG models (2000-2007). This direct-fit system replaces the restrictive OEM air box, allowing for a more efficient supply of fresh air to your engine. Its design isolates the air filter within the engine bay, ensuring it draws cooler air and performs optimally. The less restrictive design not only enhances performance but also improves the induction tone of your vehicle. Mishimoto reports proven gains of up to 10 HP due to the increased airflow. The air filter is washable, contributing to long-term usability and maintenance ease. Constructed with quality in mind, this air intake system is designed in the USA and comes with a lifetime warranty from Mishimoto, reflecting the brand's confidence in its durability and performance.
