The PB4 car powerbase here is easily differentiated by the addition of cooling vents. These vents assist in the cooling of the internal components, and will have a great benefit in warmer climates. Operationally, the V6.0 PB4 functions identically to the previous PB4, with the advantage of a slightly higher track voltage.
