Product Description

The HKS 70026-AT021 Cold Air Intake Box Kit is engineered for the Toyota GR Yaris GXPA16 equipped with the G16E-GTS 1.6L turbocharged three-cylinder engine. The dedicated intake box encloses the performance intake system to help isolate the air filter from engine-bay heat, supporting more consistent intake conditions during driving and performance use.

The kit uses CFRP for the air cleaner cover, air cleaner box, and air cleaner duct, while an integrated rain cover helps protect the intake path from water entering through the front duct. Despite enclosing the intake, the design is intended to retain the characteristic intake sound associated with a performance-oriented exposed intake system.

Installation requires the separately available HKS Carbon Racing Suction 70028-AT004. The kit supports early and later GXPA16 models as well as manual and automatic transmissions. HKS specifies an estimated installation time of approximately 1.5 hours and identifies compatibility information as current through August 2025.
