PERRIN Performance designed this Cold Air Intake System to be a direct replacement of the restrictive factory airbox. PERRIN Performance has developed this intake system to use proper MAF alignment as well as plumbing size to maintain an appropriate air-fuel ratio, as well as preventing any check engine lights. This intake system features a smooth aluminum intake pipe that reduces turbulence to promote better airflow throughout the entire RPM band. The intake pipe has also been powder coated for extra protection against rust and corrosion. Once this intake is installed, you can expect improved throttle response, and increases in both horsepower and torque. Additionally, you will notice an improved growl under wide-open acceleration.
NO Tuning Required
Fits all 2018+ STI.
