Inlet rubber for Vespa scooters - between frame and airbox. Porous or perished inlet rubbers should always be replaced. These rubbers ensure clean air reaches the air filter thereby reducing the amount of small particles entering the air filter. This helps increase the life of the motor by reducing the possibility of wear. This also prevents water ingress into the airbox. 10 ribs in length. OEM No. for comparison: 227205 / 179803.
