Review on Forrie Plastic Manifold Gaskets Compatible by Nick Moo

Great intake replacement for my high mileage F150. A few things to note (and improve): 1. There are no instructions, I already did the reception work so I knew how to take everything apart and put back together. 2. In the back corner of the collector there is a fitting closed with a rubber plug and a dirty clamp. If you are not using this coolant fitting and need to block it, REPLACE the clamp with a better one. The one supplied does not have the strength to hold the pressure cap in the system. If you need to replace the manifold and are on a tight budget, that's fine. Update 8/3/21: The intake works perfectly. . The thermostat included in the kit just failed and is stuck. Replaced with a factory Motorcraft thermostat and everything worked again.
