Grand Sport coupe models equipped with a manual transmission use a dry-sump oiling system, differential cooler and a rear-mounted battery.

The dry sump system (RPO Z52) requires a high pressure oil filter.
During an oil change, use an Ultraguard™ Gold UPF48R oil filter (part number 12626224).

This filter has a higher burst strength, which is required because the oil pump produces greater volume and high system oil pressure.
It is the same high pressure oil filter as used on the ZR1 and Z06 models.

TIP: The internal components are the same in both the UPF48R and PF48 oil filters. The UPF48R can be used in applications where the PF48 is specified.
