V08 is the corporate GM heavy-duty cooling RPO. On 3rd-gen F-body cars it brings a larger radiator core, an additional auxiliary cooling fan or larger primary fan, and a higher-flow water pump. It is required-or-strongly-recommended on cars ordered with the L98 5.7 and the WS6 suspension package, and frequently appears alongside the KC4 oil cooler on GTAs.
