Genuine Nissan Skyline R32 R33 R34 GTR GST-4 GTS4 STAGEA ATTESA AWD Accumulator 41630-20U00
This hydraulic pressure accumulator serves as a buffer for the AWD system. It dampens the pressure spikes as the AWD engages and improves the smoothness. It is composed of a bladder that is filled with nitrogen. The hydraulic pressure acts against the bladder as a cushion. It's comparable to a shock absorber for the hydraulic pressure.
