Ensure the longevity and performance of your 2003-2007 Ford 6.0L Powerstroke with the Dorman 904-207 Fuel Injector O-Ring Kit. When you service your fuel injectors, replacing the old, worn-out seals is an essential step to prevent leaks and maintain an airtight seal. Over time, the constant exposure to extreme heat, fuel, and oil can cause the original O-rings to degrade, leading to poor engine performance or even costly injector failure. Dorman’s high-quality rubber seals are engineered to be highly resistant to these harsh conditions, providing a reliable, leak-free solution for two injectors and protecting your investment.
