Add some horsepower to your 2015-2018 STI with the new Mishimoto Performance Air Intake. This kit is engineered specifically for your 2015-2018 Subaru STI and includes everything needed to replace the restrictive stock airbox. This dyno-proven air intake provides 20 whp/18 wtq gains over the stock intake while maintaining safe air/fuel ratios, perfect for some extra punch on the street or autocross course. The Mishimoto Subaru 2015-2018 STI Performance Air Intake includes everything needed for installation, installs in under one hour, and works perfectly with the stock tune. This pipe utilizes the Mishimoto air straightener and CNC-machined mass airflow sensor (MAF) housing to provide accurate and consistent MAF readings, which translates into a smooth power band. To reduce air intake temperatures (IATs), the air filter has been placed outside the hot engine bay, and a powder-coated heat shield prevents any heat-soak from occurring.
