These valve stem caps looked really nice on my new 2019 Genesis G80. However, within 18 months, the valve stem caps were so rusty that when I took my car in for service to add air, the auto mechanics could not remove the caps. They told me the only way to fix the problem was to replace the entire valve stem. As many of you know, this can get very expensive. However, since I work in the trades, I was able to remove these with a cordless saw by cutting through the side of the valve without cutting the threads on the valve. So if you do decide to buy one, be sure to use an anti-seize lube and check it monthly.
