Review on Dorman 555 097 Steel Expansion Plug by Reco Vasquez

Through trial and error, I found that this steel expansion plug is a fitting addition to my high-performance car. It's durable, easy to install, and fits snugly, preventing leaks. The steel construction also eliminates the risk of cracking under high temperatures. However, I had to sand down the edges a little to make a perfect seal. Overall, it's an affordable and reliable option for people who want to keep their engine in top shape.
