My analysis of this automotive gasket showed that it did not live up to its claims of ultra seal. Despite being marketed as a high-quality gasket, it failed to prevent leaks between the manifold and the engine block. The only pro I could think of is that it was easy to install. However, the cons outweighed this benefit as I had to replace it soon after installation. Overall, I do not recommend this gasket for anyone looking for a reliable and effective sealing solution.
