HKS Premium Suction Intake Kit - 2013-2021 Scion FR-S / Subaru BRZ / Toyota

Premium Suction Intake Kit for the 2013-2021 FR-S, BRZ, and Toyota 86

The HKS Premium Suction Intake Kit for the 2013-2021 Scion FR-S, Subaru BRZ, and Toyota 86 is a step up from the Racing Suction in terms of intake routing and charge temperature management. The Premium Suction uses a specifically designed intake pipe and filter configuration that better isolates the air intake from underhood heat sources compared to the standard Racing Suction setup, while maintaining the induction sound character that makes an open intake worthwhile on the high-revving FA20.

Specs & Highlights

• Premium intake pipe and filter system
• Improved heat isolation versus Racing Suction
• Replaces factory airbox and intake tract
• Maintains induction sound character at high RPM
• All hardware included
• Fitment: 2013-2021 Scion FR-S / Subaru BRZ / Toyota 86

70mm Pipe, 5-10°C Lower Intake Temp Than Racing Suction

The Premium Suction uses the same 70mm diameter inlet pipe as the Racing Suction but with a revised routing that positions the filter further from the engine's heat sources, reducing the intake air temperature penalty. Under sustained driving conditions, documented intake air temperature is approximately 5–10°C lower than the Racing Suction and approximately 3–8°C above ambient, a meaningful improvement for a hot engine bay environment. The heat shield included in the kit further reduces radiant heat transfer to the intake pipe.

Heat Isolation Improvement and the Included Heat Shield

The heat isolation improvement matters for consistent power output. An intake that picks up hot underhood air delivers less dense charge air to the engine, which reduces effective power. Particularly on a warm day or after extended spirited driving when engine bay temperatures have risen. The Premium Suction's routing addresses this more completely than a basic short-ram intake.

Street-Oriented Intake Upgrade with Temperature Management

The Premium Suction is appropriate for naturally aspirated FA20 builds as well as the starting point before adding the HKS GT2 Supercharger or bolt-on turbo kit. The intake system quality should match the power level of the rest of the build.

The FT Breakdown

The Premium Suction is the street-oriented intake upgrade for the FA20. Better than the Racing Suction in temperature management, appropriately priced for the improvement it provides. If you want the induction sound and the airflow improvement with reasonable charge temperature management on a street-driven car, the Premium Suction is the right choice. The 5–10°C temperature improvement of the Premium Suction over the Racing Suction is meaningful in the context of FA20 naturally aspirated power — a 5°C charge air temperature reduction translates to approximately 0.5% air density improvement, and at 7,000+ rpm on a track session where the engine bay has been heat-soaking for 20 minutes, the compounding effect over multiple laps produces measurable power consistency improvement.
