Our engine components are OEM Ford and not an off brand offered by other companies. We highly suggest the use of new OEM Ford Motorcraft parts and accessories when replacing internal engine components and gaskets. Many other companies use cheaply made replacements which are not what you want to put in the engine you are repairing or rebuilding. If you have had a catastrophic failure of your factory engine keep in mind many small particles of metal will travel through your entire oiling system including your variable cam timing components. Do not risk your new engine or engine repair by using potentially contaminated factory components.
