Shield the inlet from engine-bay heat and feed it fresh air
HKS 70026-AT020 combines the renewed cold-air box with Carbon Racing Suction hardware for the GXPA16 Toyota GR Yaris. The sealed layout isolates the filter from engine-bay heat and directs outside air through large-capacity ducts.
Key Features
- HKS 70026-AT020 includes the cold-air box and Carbon Racing Suction as a full kit.
- The enclosure separates the filter from hot engine-bay air.
- Large ducts route fresh air toward the filter.
- A front-duct rain shield helps limit water ingress.
- Autoclaved dry-carbon parts use 3K twill weave with gloss clear coat.
