As a hesitant buyer, I was pleasantly surprised by the performance of this gasket. As a result of using this product I found that the overall engine performance was enhanced. Not only did it improve the seal around the valve cover, but it also increased the lifespan of the gasket. The installation process was easy and straightforward. However, the only downside is that it might be slightly expensive than other similar products in the market. Overall, I highly recommend this gasket for automotive enthusiasts who want to enhance their car's performance. .
