Installed these in my 2014 Touareg wheels (actually 2014 Cayenne wheels are 18"), function tested before installation as I'm from cheap ebay was scorched. Dealing with OEM sensors that were DOA but only discovered after installation. They match the Cayenne wheels well, although they don't sit perfectly flush against the inside of the wheel like the OEMs do. You will be activated on the 1/10 mile TPMS system, amazing! Highly recommended for this price.
