HKS Racing Suction Intake ZN6/ZC6 FA20 - 2013-2016 Scion FR-S / Toyota GT 86 / 13-21 Subaru BRZ

Let the FA20 in your FR-S, BRZ, or 86 breathe better with the HKS Racing Suction Intake. Designed to improve intake airflow, sharpen throttle response, and add a more aggressive induction sound, this intake is a great upgrade for owners who want a more engaging driving experience without overcomplicating the setup.

The HKS Racing Suction Intake uses a short suction pipe, airflow adapter casting, heat insulator, and shroud design to help stabilize intake air temperatures while allowing the engine to pull in air more efficiently. The result is stronger high-RPM power, better response when opening and closing the throttle, and a more direct engine sound that makes the FA20 feel more alive.

Key Features

• Improved Intake Airflow: Helps the FA20 breathe more efficiently for better response and high-RPM performance.
• Added Induction Sound: Gives the car a more engaging intake tone without relying on the factory sound creator.
• Short Suction Pipe Design: Supports quicker throttle response and a more direct intake path.
• Heat Insulator Included: Helps shield the intake from hot air near the radiator.
• Fresh Air Shroud Design: Helps guide cooler outside air toward the intake for more stable intake air temperatures.
• Easy Installation: Designed as a straightforward intake upgrade for compatible FA20 vehicles.
• HKS Engineering: Developed by one of Japan’s most trusted performance brands.

Why We Like It

This is a great intake for owners who want more sound and response from their FA20 without making the car feel overly modified. The Racing Suction setup adds a sharper intake character, improves airflow, and gives the engine bay a cleaner performance look with classic HKS quality.

HKS Design Notes

According to HKS, this intake is designed to deliver stronger high-RPM power and improved throttle response through the use of an airflow adapter casting, short suction pipe, and heat insulator. By blocking hot air from the radiator and using a shroud to guide fresh air to the filter, the system helps stabilize intake air temperatures while delivering a more direct engine sound.
