This gasket IS a game changer when it comes to automotive performance. As my tests showed, the Fel Pro gasket provided a perfect seal, keeping oil from leaking and preventing overheating .The gasket was easy to install and, unlike other gaskets I've tried, did not show signs of wear and tear after hard driving. The only con is that it is a bit pricier than other gaskets on the market, but the extra cost is definitely worth it for the added performance..See full review
