Review on Flappers Shutters 807166A1 Mercruiser Maniflold by Robert Carlson

As an automotive enthusiast, I have tried several replacements for my Mercruiser Manifold and tried the Flappers Shutters 807166A1 through my rigorous testing .The result speaks for itself: it has outstanding performance that promises better engine cooling even in extreme conditions. I also appreciate that the installation is simple, which saves a lot of time. Admittedly, the product can be a bit pricey, but for its excellent quality, it's worth every penny..
