Description

The HKS Cold Air Intake Full Kit is a comprehensive, high-performance induction system designed to unlock a more responsive and efficient airflow path for the FA24 engine. More than just a filter upgrade, this complete kit includes a strategically designed airbox, a high-strength carbon fiber suction pipe, and a high-flow intake duct. It works in harmony to reduce intake air temperatures, minimize airflow resistance, and deliver tangible gains in throttle response and power, all while maintaining a refined engine bay aesthetic and street-safe reliability.

Product Highlights

🌬️ Trio of Performance – Complete System Approach
This is not a simple filter swap. The kit’s three core components—the airbox with Super Power Flow filter, carbon suction pipe, and high-flow duct—are engineered together to function as a unified system, maximizing intake efficiency and thermal management for real-world performance benefits.

❄️ Engineered for Cool, Stable Air
The enclosed airbox design strategically shields the high-flow filter from engine bay heat. By drawing cooler, denser air from the factory intake location, the system helps maintain lower and more stable intake air temperatures (IATs), a key factor in consistent power output, especially during repeated spirited driving.

⚡ Optimized Flow Path for Improved Response
Every component is designed to smooth and accelerate airflow:

• The intake duct features a blow-molded, seamless interior with a crucial 87.5mm diameter at its narrowest point—a significant increase over the stock ~50mm restriction—dramatically reducing high-RPM airflow resistance.

• The carbon suction pipe boasts a smooth inner surface crafted via a high-pressure molding process, ensuring air travels to the throttle body with minimal turbulence.

• Retaining the factory air flow meter position ensures compatibility with OEM engine management for reliable drivability.

🔧 Premium Materials & Refined Aesthetics

• The carbon suction pipe is a work of engineering, constructed with 3K twill carbon and internal UD layers for both visual appeal and high strength that resists deformation under vacuum.

• The airbox features a clear smoke upper case, offering a subtle showcase of the iconic HKS Super Power Flow filter while maintaining a tidy, performance-focused engine bay look.
