This gasket is a game changer for automotive enthusiasts like me. Based on my observations, the Felpro VS21566C Valve Cover Gasket is incredibly easy to install and guarantees a perfect seal... I've been using it for a couple of months now and it has performed flawlessly, keeping my engine oil in check and ensuring a smooth ride. The only downside is that it's a bit pricier compared to other gaskets in the market, but the quality definitely makes it worth it..
