I have a CRV and a VW Touareg.Currently i am in the process of deciding if i want to add a Cayenne to the family.I dont know for sure yet though.I used the sylvania silverstars for the CRV and i am looking into HIDs and xenonmatch for the VW Touareg.Here is the site for them www.sylvania.com. I hope this helps some.sorry if dont have a Cayenne at the moment but i am still debating.I can definently say that i did get the cayenne roof rails for the Touareg and that was the best purchase i ever made.
