Improve your engine's volumetric efficiency and throttle response with the HKS Racing Suction (RS) Intake System. Designed specifically for the Subaru WRX STI (VAB/VAF) equipped with the EJ257 engine, this kit replaces the restrictive factory airbox with a high-flow HKS Super Power Flow filter and a mandrel-bent aluminum suction pipe. By smoothing the intake path and reducing resistance, the 70020-AF108 kit allows the turbocharger to draw air more freely, resulting in improved performance and a more aggressive intake sound.

  • Features the HKS Super Power Flow reloaded filter for maximum surface area and filtration efficiency
  • Mandrel-bent aluminum piping eliminates the turbulence found in factory corrugated plastic hoses
  • Vehicle-specific heat shielding or mounting brackets included for a secure, bolt-on fit
  • Designed to work with the factory MAF sensor calibration on EJ257 powerplants
  • Genuine HKS component made in Japan
  • Manufacturer Part Number: 70020-AF108
