Description

The HKS Cold Air Intake Kit delivers a focused and intelligent upgrade for the GR86/BRZ’s intake system, prioritizing thermal management and stable performance. By encasing the legendary HKS Super Power Flow air filter within a model-specific airbox, this kit effectively shields intake air from engine bay heat. The result is a cooler, denser air charge that translates into sharper throttle response and more consistent power, all while maintaining perfect compatibility with factory engine management and a clean, under-hood appearance.

Product Highlights

📦 Focused Thermal Management – The Enclosed Advantage
The core innovation of this kit is its dedicated intake box. Unlike exposed “short ram” intakes that draw hot air, this enclosure isolates the high-flow Super Power Flow filter from engine bay temperatures. This strategic design significantly reduces intake air temperature (IAT), as proven by internal HKS testing, ensuring the engine breathes cooler, denser air for more consistent performance.

🌬️ Optimized Flow with OEM Reliability
Performance is achieved without compromise. The kit retains the factory air flow meter in its original position, ensuring seamless integration with the vehicle’s ECU for flawless drivability and error-free operation. The addition of a dedicated side duct reduces intake airflow resistance, improving efficiency over the stock system.

⚙️ Proven Performance Filter – Super Power Flow
At the heart of the system is the iconic HKS Super Power Flow air cleaner (Φ150-80mm, wet two-layer). Renowned for its high filtration quality and excellent airflow, this reusable filter is the trusted choice for performance enthusiasts worldwide, now housed within a more efficient thermal environment.

✨ Subtle, Purpose-Built Aesthetics
The airbox features a clear smoke-colored upper case. This design choice subtly showcases the distinctive HKS filter within, adding a touch of performance style to the engine bay while maintaining an overall tidy and engineered look.

Technical Specifications

• Product Name: Cold Air Intake Kit

• Model Code: 70026-AT010

• Compatibility: Toyota GR86 / Subaru BRZ (ZN8/ZD8, FA24, October 2021+). *Not compatible with Cap Car Basic (one-make race) vehicles or the HKS GT2 Supercharger Kit.*

• Kit Configuration: HKS Super Power Flow Air Cleaner + Intake Box (Upper/Lower Case) + Side Duct.

• Air Filter: HKS Super Power Flow (Φ150-80mm, wet two-layer, cleanable/reusable).

• Key Design: Enclosed airbox system for reduced intake air temperature.

• Airbox Material: Plastic construction with clear smoke upper lid.

• Estimated Installation Time: 1.5 hours (Professional installation recommended).

Performance Philosophy

• Goal: To provide a measurable and reliable improvement in intake efficiency by solving the primary limitation of the stock system: heat soak. The focus is on stable, repeatable performance gains and improved throttle response through thermal management, rather than just increased airflow volume.

• Focus: A smart, single-component upgrade that offers the best of both worlds: the proven flow of an HKS performance filter with the thermal advantages of a sealed airbox. It’s the ideal choice for those seeking a performance bump without moving to a fully exposed intake or a complex multi-part system.

Installation & Usage Notes

• 🔧 Straightforward Installation
  Designed for easier installation than full intake systems, with an estimated time of 1.5 hours. Professional installation is still recommended to ensure all seals are properly fitted and the system is airtight.

• ⚠️ Important Compatibility & Care Notes

  • This kit is NOT compatible with the HKS GT2 Supercharger Kit.

  • This kit is NOT for use on “Cap Car Basic” one-make race vehicles.

  • Care Instructions: The clear airbox lid may have minor circular marks or cloudiness from manufacturing; this is normal. Do not use organic solvents for cleaning, as they can damage the resin.

• 🧼 Maintenance
  The included Super Power Flow filter requires periodic cleaning and re-oiling according to HKS specifications to maintain optimal performance and filtration.
