Description

The HKS Racing Suction is a high-performance intake system. It is engineered to enhance the mid-range torque and auditory character of the Nissan GT-R R35. Additionally, it maintains top-end power and stable intake temperatures. By replacing the restrictive factory airbox with twin HKS Super Power Flow filters, this kit provides a noticeable increase in responsiveness. These filters are positioned within the radiator grille.

Moreover, it offers a thrilling sporty intake sound. This makes it an ideal upgrade for both spirited street driving and track use.

Product Overview & Purpose

This system focuses on improving the crucial mid-range driving experience. It replaces the factory airbox assembly with high-flow conical filters. These filters draw cooler, denser air from the front grille area. As a result, drivers experience more immediate throttle response.

There is a tangible increase in mid-range torque. It provides an exhilarating turbo induction sound, all while preserving the high-RPM power of the stock system. Furthermore, it minimizes impact on radiator airflow.

Product Highlights

⚡ Enhanced Mid-Range Torque & Response
Internal testing confirms the Racing Suction’s primary benefit: a significant boost in mid-range torque. Measured gains reach +21.2 N·m (2.2 kgf·m). This translates to stronger, more responsive acceleration in the 3,000-5,000 RPM range. It represents the “sweet spot” for daily driving and backroad enjoyment, where the driver feels the improvement most.

🎵 Sporty, Engaging Intake Sound
It unleashes a moderately sporty and exhilarating intake sound. This sound amplifies the turbo spool and engine induction noises. It is pronounced enough to heighten the driving experience, especially under acceleration. Yet, it remains refined enough for daily use. As a result, it lifts spirits without causing drone.

🌬️ Efficient & Stable Airflow Design

• Grille-Mounted Filters: The twin Super Power Flow filters (Φ150-80, Red) are strategically positioned inside the front radiator grille. This placement provides a direct path for cool, ambient air, stabilizing intake air temperatures (IAT) and preventing heat soak from the engine bay.

• Minimized Radiator Impact: The design carefully considers airflow to the radiator and intercoolers, aiming to have as little adverse effect as possible on their cooling efficiency.

🔧 Foundation for Further Upgrades
This kit serves as an excellent standalone upgrade and also acts as the perfect foundation for the more advanced HKS Premium Suction Kit (70018-AN007), which can be added later for even greater airflow and power potential.
