The new Mishimoto Performance Air Intake is engineered specifically for your Subaru STI 2015-2018.
This kit includes everything needed to replace the restrictive stock air box.
Our engineers spent months fine-tuning this design to extract every last bit of performance.
This air intake is dyno-proven to provide gains of 20 whp and 18 wtq over the stock intake while maintaining safe air/fuel ratios, ideal for extra punch on the street or autocross course.
The Mishimoto Subaru 2015+ STI Performance Air Intake includes all necessary components for installation, installs in under one hour, and works perfectly with the stock tune.
The mandrel-bent aluminum intake pipe is available with a red or black powder-coated finish or a polished aluminum finish.
This pipe utilizes the Mishimoto air straightener and CNC-machined mass airflow sensor (MAF) housing to ensure accurate and consistent MAF readings, which translates into a smooth power band.
To reduce air intake temperatures (IATs), the air filter is placed outside the hot engine bay, and a powder-coated heat shield prevents heat-soak.
The Mishimoto free-flowing air filter provides a 16% greater surface area, optimal airflow, and proper filtration of dirt and debris.
The included Mishimoto oiled air filter is completely serviceable for a lifetime of reliable use.
Additionally, this kit includes a silicone coupler, clamps, and all other hardware necessary for a quick installation for easy bolt-on power.
A rubber cap is provided to cover the sound symposer housing.
Along with an upgrade in power, this intake also offers an aggressive and rich intake tone that significantly improves over the stock intake.
The Mishimoto Subaru WRX/STI Performance Air Intake is designed in Delaware, USA and includes the Mishimoto Lifetime warranty.
