The universal oil catch tank is designed to protect the engine and improve its performance by condensing the oil vapors that enter the intake through the pneumothorax and are then sucked into the combustion chambers. They form a carbon deposit on the throttle and in the intake manifold, which results in a reduction in power. Diameter of connectors and cable - 9mm. Mounting brackets included.
