This is the optional pressure chamber set from Mugen. This pressure chamber is generally used for on-road cars between the tuned pipe pressure nipple and the tank lid to stabilize back pressure during acceleration and braking. Sometimes it can be useful for off-road cars to stop sudden flame out when leaving pit row when the tank lid is closed. You will need to retune the bottom end of your engine if you install one of these pressure chambers.
