HKS 70029-AN001 Intake System CFRP for NISSAN Skyline GT-R (R32) 1989-1994

The Advanced Heritage Concept intake system is now finally in the market! Ultimate high-efficiency intake system.

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 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.

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. This enhancement was observed during the 600ps phase.

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%.
