Review on Enhance Performance with BBK 1572 65/70mm Throttle Body Gasket Kit for Ford 5.0L by Shawn Sims

Material too tight around main body to ensure proper sealing. Despite clean surfaces and up to 25 ft-lbs of torque, coolant leaked into the top intake. I didn't notice until the engine stalled and coolant leaked out of the tailpipe; I hope I haven't blocked the pistons. Upon removing the gasket, I noticed that the material moved just a hair, but that's enough for a significant amount of pressurized coolant to fill the top inlet in just a few minutes. Unless you're bypassing the EGR or coolant fittings, I don't recommend these gaskets!
