Installation Notes and Tips

Verify the filler neck style before ordering, since this cap uses a threaded cam design and is specified as non-vented. Confirm the thread diameter, shell diameter, and depth against the original cap for proper fitment. For body-style and model-specific applications, use the vehicle listing to match your exact year and model, such as Fits 2015-2019 Chevrolet Volt, N/A; Fits 2017 Porsche 718 Boxster, N/A; and Fits 2004-2010 Volkswagen Touareg, N/A.

Additional fitment examples include Fits 2007 Audi Q7, N/A; Fits 2006 Porsche Cayenne, N/A; and Fits 1997-2012 Porsche Boxster, N/A. Always compare the original cap’s venting and locking style before installation.
