HKS Racing Chamber Kit for Skyline GT-R (BNR34/BCNR33)

The chamber pipe from each turbine exit to the collecting part is made of aluminum pipe.
By following the genuine layout, it supports a wide range of tuning menus.

It is designed so that the inflow air can join more smoothly at the gathering part of the chamber pipe, and by reducing the intake resistance, the original potential of the engine is brought out. In addition, by using aluminum pipes with a mirror hub finish for the chamber pipes, it contributes to the dress-up of the engine room.
It can be used in combination with stock air cleaner box (requires modification), super power flow reloaded, and racing suction reloaded. It corresponds to various menus from boost up to sports turbine specification.
