tHE Dorman 555 104 Steel Expansion Plug is the perfect engine component for high-performance vehicles. According to my experience, it is durable and made of high-quality materials making it last a long time. This product helped me improve my cars engine performance and I am satisfied with its overall function. The only con I could think of is that it may not fit all types of engines, so be sure to check compatibility before purchasing. .
