Features & Specifications:

  • Advanced Heritage CFRP Intake System 70029-AN001
  • Engine: RB26DETT
  • CFRP (Carbon Fiber Reinforced Polymer) is utilized for the primary components, including the piping and air cleaner box, to achieve a weight reduction of approximately 65% compared to the factory intake system. For enhanced heat resistance, a high heat-resistant prepreg with a temperature resistance of 350°C or higher is employed for the chamber pipe after supercharging and the suction pipe near the turbine, as these components are exposed to high temperatures.
  • The cleaner box has also been specially designed with CFRP, contributing to weight reduction. The air filter surface area has also been increased by approximately 6% to improve intake efficiency. The air flow sensor is not a stock component which increases the pipe diameter.
    The entire layout has been reviewed to achieve higher efficiency and a dedicated washer tank is also included in the kit.
  • The pressure loss has been significantly decreased by 46% compared to the previous installation of the HKS special piping kit. This improvement is achieved through an enlarged suction capacity and an increased cross-sectional area for introducing outside air. The dual intake ducts allow for approximately 2.4 times more air to enter than the stock system. 
  • The enclosed design minimizes the intake of hot air into the engine compartment, resulting in a reduction of up to 60% in intake air temperature during WLTC mode when compared to the exposed HKS Super Power Flow system.
  • An anti-surge plate, also known as a surge suppression rectifier plate, has been installed in the suction pipe to address the issue of intake air interference, which has been a persistent problem in the RB26 twin-turbo layout. This plate effectively increases the margin for intake air flow, helping to prevent surging and maintaining optimal performance.
  • The geometry of the 2-in-1 chamber pipe has been optimized to ensure consistent operating conditions for both the front and rear turbines. This improvement results in a more balanced flow and performance. In comparison to conventional HKS special piping kits, the flow discrepancy between the front and rear turbines has been reduced by an impressive 90%.
