Show original supplier description
The Mishimoto Performance Air Intake system is engineered to provide a significant boost in power, styling, and durability for the 2013-2018 Ford Focus ST. This intake system is designed as a direct fit, ensuring a straightforward installation process. It boasts a 3-inch mandrel-bent aluminum pipe, which is crucial for optimizing airflow to the engine. Buyers can choose between a polished or a wrinkle black powder-coated finish to match their desired aesthetic. Significant performance enhancements are a key feature, with dyno-proven maximum gains of up to 6 wheel horsepower (whp) and 5 wheel torque (wtq) reported on the stock tune. The airbox design plays a vital role in performance by keeping unwanted hot engine bay air from entering the air filter. It strategically utilizes the stock cool air duct to further lower intake air temperatures. The placement of the air filter is optimized to receive maximum airflow directly from the front of the vehicle, contributing to improved throttle response and overall power output. This kit includes everything necessary for installation, including an IAT adapter specifically for the 2016 model year. The highly aggressive intake tone under acceleration is another appealing characteristic for enthusiasts. Mishimoto backs this product with their renowned Lifetime Warranty, ensuring long-term reliability and performance.
