Description

■Performance Data

The HKS Cold Air Intake Full Kit represents the pinnacle of intake system engineering for the GR Corolla, combining the high-flow performance of the Carbon Racing Suction with a fully enclosed, ducted airbox for maximum thermal efficiency. This complete system is engineered to deliver stable, cool air to the turbocharged G16E-GTS engine, unlocking consistent power and response by completely isolating the filter from engine bay heat. Crafted from premium dry carbon fiber, it provides a dramatic reduction in intake air temperature (IAT), proven to be 8.9°C cooler on average than the Racing Suction alone during circuit driving.

Product Overview 

This kit solves the primary limitation of open-element intakes: heat soak. By integrating the Carbon Racing Suction components into a sealed airbox fed by dedicated front air ducts, it creates a true Cold Air Intake (CAI) system. This ensures the engine consistently breathes the coolest, densest air possible—directly translating to more stable power output, especially during repeated hard driving or in hot conditions—while retaining the auditory and visual benefits of carbon fiber.

Product Highlights

❄️ Proven Thermal Management for Stable Performance
Circuit testing at Fuji Speedway delivered definitive results: The enclosed airbox system maintained an average intake air temperature of only 8.9°C during a hot lap. This was 16.5°C cooler than the open Racing Suction and 8.9°C cooler than even the stock airbox, demonstrating its exceptional ability to block engine bay heat and supply cooler, denser air to the turbocharger for consistent power.

🔧 Complete System Integration & Airflow Optimization
This is a comprehensive upgrade that includes everything:

• Carbon Racing Suction Core: The high-performance carbon intake pipe and heat shield.

• Enclosed Carbon Airbox & Cover: A dry carbon box that fully seals the Super Power Flow filter.

• Dedicated Front Air Ducts: Large-capacity upper and lower ducts efficiently route fresh, ambient air from the front grille directly into the sealed airbox.

• Rain Cover: Provides protection for the front duct, ensuring safe operation in all weather conditions without risk of hydro-lock.

✨ Premium Autoclave Dry Carbon Construction
All CFRP components are produced using the high-end autoclave method, resulting in parts that are extremely lightweight and strong. The surfaces feature a flawless 3K twill carbon weave with a glossy clear coat, matching other HKS carbon parts to create a cohesive, race-inspired aesthetic in the engine bay.

🎵 Retained Performance Character & Sound
While focusing on thermal management, the system retains the exhilarating sporty induction and turbo spool sounds characteristic of the Super Power Flow filter, delivering an engaging sensory experience alongside measurable performance benefits.

Installation & Usage Notes

• 🔧 Professional Installation Highly Recommended
  Installation is more involved than a simple pipe swap, requiring fitting the air ducts, airbox, and ensuring all seals are perfect. Professional installation is highly recommended to guarantee the system is airtight and functioning as a true sealed CAI.

• 🛡️ All-Weather Usability
  The included rain cover ensures the system can be used safely in all conditions, addressing a common concern with open-front air ducts.

• ⚙️ Ultimate Supporting Mod for Power & Tuning
  This kit forms the perfect intake foundation for any level of tuning. It pairs ideally with:

  • Exhaust Systems: Like the HKS LEGAMAX Sports to improve turbo spool and exhaust flow.

  • Intercooler Upgrades: To further cool the charged air.

  • Engine Tuning: To fully capitalize on the improved, stable, and cooler airflow.
