2013–2019 Scion FR-S, Subaru BRZ & 2017–2019 Toyota 86 FA20 Engine
70999-AT002
Overview:
The HKS Air Intake Duct is a direct replacement component designed specifically for the Scion FR-S (2013–2016), Subaru BRZ (2013–2019), and Toyota 86 (2017–2019) equipped with the FA20 engine. This upgraded duct replaces the original equipment manufacturer (OEM) intake duct with a larger, lighter, and stronger alternative that enhances airflow consistency to the engine’s intake system. Ideal for enthusiasts seeking improved engine breathing without extensive modifications, the HKS duct maintains compatibility with the OEM airbox and all necessary factory parts, ensuring a seamless upgrade experience.
By optimizing airflow into the intake location, this duct supports both naturally aspirated and forced induction setups that retain the OEM intake box position. Its refined design not only boosts performance potential but also contributes to a cleaner engine bay appearance.

Construction & Design:
The HKS Air Intake Duct is crafted from premium-grade plastic that balances lightweight properties with structural integrity. This material choice ensures the duct withstands heat and vibration typical of engine compartments while contributing to overall vehicle weight reduction. The design features a larger cross-sectional area than the OEM duct, promoting smoother and more efficient airflow into the intake system. Precision engineering allows it to fit perfectly within the factory intake location, preserving the original layout and mounting points for a clean, professional installation.
Installation & Fitment:
Installation of the HKS Air Intake Duct is straightforward and requires no special tools or modifications. It is a direct bolt-on replacement for the OEM duct on the specified models, preserving all factory mounting points and connections. The duct works seamlessly with the stock airbox or aftermarket intakes that utilize the OEM intake location. Because it maintains full compatibility with factory sensors and components, it does not cause any check engine lights or require ECU recalibration.
