Reduced Intake Restriction
The factory Subaru turbo suction pipe uses a moulded resin design with bends and flexible sections that can introduce airflow resistance.
The HKS Premium Suction Kit replaces this section with a smoother polished aluminium pipe, helping provide a more direct airflow path from the airbox towards the turbocharger compressor inlet.
HKS Super Air Filter Included
The kit includes an HKS Super Air Filter, designed to provide increased airflow while maintaining effective filtration performance.
This allows the factory airbox to be retained, making the Premium Suction Kit a clean and practical intake upgrade for street-driven and performance-oriented Subaru builds.
Premium Engine Bay Appearance
As well as improving the intake path, the polished aluminium suction pipe provides a much cleaner and more performance-focused engine bay appearance compared with the original black resin intake components.
Factory ECU Friendly
The Premium Suction Kit is designed around the original Subaru intake system and retains the factory airbox, making it suitable for customers looking for a straightforward bolt-on intake upgrade.

Important Fitment Information
Please confirm your vehicle chassis code, engine code and production date before ordering, as compatibility varies between Subaru model and engine combinations.
