## Description

Prevents leakage between two objects

Review: Great product - Just as described perfect fit
Review: OEM Motorcraft part - Replaced this thermostat gasket while doing an intake manifold swap and decided to stick with Motorcraft for peace of mind. Fit was spot on and installation went smoothly. Everything lined up perfectly with no leaks or issues. It’s a solid OEM part — you can tell the quality difference compared to some of the aftermarket stuff out there. Engine temps have been right where they should be since the install. If you’re already doing work under the hood, this is a great time to throw one of these in. Genuine part, great fit, no hassle.
