Description

The HKS Premium Suction is a precision-engineered intake pipe kit. It is designed to eliminate a critical airflow restriction between the factory airboxes and the turbochargers on the Nissan GT-R R35.

By replacing the stock plastic inlet pipes with wider-diameter, specially cast and buffed aluminum pipes, this kit reduces intake resistance. It also improves throttle response and supports higher power levels—especially when boosting up. It’s a subtle yet highly effective upgrade favored by knowledgeable enthusiasts for its proven performance and impeccable craftsmanship.

Product Overview & Purpose

This kit targets a specific bottleneck in the GT-R’s intake tract. Specifically, the factory inlet pipes that connect the air filters to the turbochargers. These stock components are often a restriction, particularly in modified vehicles.

The Premium Suction replaces them with larger, smoother aluminum pipes. As a result, air flows into the turbos with less turbulence and restriction. This leads to improved turbo spool characteristics, increased airflow potential, and a stronger foundation for tuned performance.

Product Highlights

🌬️ Increased Diameter for Reduced Restriction
The core of the upgrade is the increase in pipe inner diameter from the stock φ45mm (φ50.5mm on 2011+ models) to a full φ53mm. This significant enlargement reduces intake airflow resistance. Additionally, it directly addresses a bottleneck that can limit performance, especially when increasing boost pressure.

⚙️ Precision Cast Aluminum Construction
The pipes are not simple bent tubing; they are specially designed and cast from aluminum. This manufacturing process allows for complex, optimized shapes with smooth internal transitions. These promote laminar airflow. Each pipe is meticulously hand-buffed to a beautiful finish. This reflects HKS’s commitment to craftsmanship, even on components mostly hidden from view.

🔧 Designed for Synergy & Power Potential
This kit is engineered to work in perfect harmony with other modifications:

• With Factory Airboxes: Can be used with stock airboxes and filters for a refined, OEM+ upgrade.

• With HKS Racing Suction: The ideal complement to the Racing Suction kit (70020-AN107). Replacing both the filters and the inlet pipes creates a fully optimized intake path from the grille to the turbo, maximizing flow and performance gains.

• For Tuned Vehicles: Essential for supporting increased airflow demands from cars running higher boost levels via ECU tuning.

Technical Specifications

• Product Name: Premium Suction

• Model Code: 70018-AN007

• Compatibility: Nissan GT-R R35 (VR38DETT, December 2007 onward). Compatible with CBA and DBA models.

• Kit Includes: Two specially cast and buffed aluminum inlet pipes, necessary couplers, and clamps.

• Key Specification: φ53mm inner diameter (vs. stock φ45/φ50.5mm).

• Key Benefit: Reduces intake restriction between airbox and turbo, improving response and flow.

• Synergy: Perfectly complements the HKS Racing Suction (70020-AN107).

Performance Philosophy

• Goal: To provide a fundamental, hardware-based improvement to the intake system’s flow capacity by addressing a known factory restriction with over-engineered components. The focus is on precision, efficiency, and enabling higher performance levels.

• Focus: A critical supporting modification for the tuned GT-R and a favorite of connoisseurs. It is designed for owners who understand the importance of removing sequential bottlenecks in the intake path and who appreciate the hidden quality of a perfectly crafted component, even if its beauty is mostly for the installer’s eyes.

Installation & Usage Notes

• 🔧 Professional Installation Recommended
  Installation requires removing the factory inlet pipes, which involves working in the tight spaces around the turbos and intercooler piping. Professional installation is recommended to ensure perfect fitment, airtight seals on all connections, and proper routing.

• ⚙️ Ultimate Intake System
  For the ultimate intake upgrade, install this Premium Suction kit together with the HKS Racing Suction. This two-stage approach replaces the entire intake path from the front grille to the turbo inlets with high-performance components for maximum flow and thermal efficiency.
