OVERVIEW

Upgrade your existing induction setup with the HKS Cold Air Intake Box Kit, specifically engineered for North American specification vehicles. This kit allows drivers who already own an open-element HKS Racing Suction intake system to fully enclose it inside an autoclave-produced dry carbon fiber thermal isolation box. By sealing your filter away from radiant underhood heat, this expansion assembly captures cold ambient air from outside the engine compartment to minimize intake air temperatures (IATs), ensuring your turbo delivers consistent track-day performance. Note: This is an expansion box kit and does not include the air filter or aluminum induction piping. It is a USDM market exclusive featuring a re-engineered lower air duct tailored to clear US-spec headlight backing structures.

FEATURES

• Premium Dry Carbon Isolation Box: Fabricated using ultra-lightweight, high-strength twill weave CFRP with a premium glossy clear coat finish for high-end engine bay styling.
• Modular Box Upgrade: Engineered strictly as a bolt-on containment upgrade to convert an open HKS Racing Suction system into a fully isolated cold air box circuit.
• USDM-Specific Clearance: Features a custom-molded lower fresh air duct designed around the precise structural footprint of North American spec headlight backings.
• Thermal Barrier Protection: Greatly limits heat-soak spikes during idling or stop-and-go traffic by entirely separating the filter element from the warm engine bay environment.
