Porsche Valve Spring Retainer For Porsche Cayenne (2004-2018) Models.

Compatibility: This valve spring retainer is designed to fit Porsche Cayenne models manufactured between 2004 and 2018. (Note: It's important to verify the exact engine code and sub-model compatibility as there may be variations. If that information is available, include it.)
