My engine was looking a little dull and outdated until I upgraded with this new coolant thermostat housing assembly. Not only does it add a shiny new accent, but it also functions perfectly and fits like a glove on my Mustang. I was a little intimidated by the installation process, but with a little patience and some YouTube tutorials, I was able to get it done. Overall, a great upgrade for anyone looking to add some "bling" to their engine while also improving functionality.
