    Racing Suction Intake System

    HKS sought to improve on the factory intake system on the STI due to the turbulent OEM piece. Replacing the corrugated section is a smooth intake pipe that will direct air efficiently to the turbo. The new and improved Stealth Frame increases surface area by 27% and improves efficiency. The intake can be ran with the air duct on the stock tune, however, a tune is recommended to maximize performance, or if you choose to remove air duct.
