When changing your UVCH gaskets, change the harness too. The ONLY negative is these are made in China...I'm sure they work fine and are OEM, but I've got to take a star off for this.

i took the valve cover off to do glow plugs. harness was loose replaced harness instead of doing the .50 mod, glad i did this part fits much tighter no more worries. solid product as usual thanks again clay

Ford has updated and improved the plug at the gasket with this harness making the .50 mod unnecessary. Just wish they would have done it that way from the beginning. Also, best prices and customer service anywhere, hands down.

I was told by 3 different people not to use aftermarket UVCH or gasket. I found both OEM here at Riffraff,They shipped fast, good protective packaging. Both parts fit perfect.

works just fine

Works good, perfect fit.

Solves the problem of the temporary .50 mod, that was not a permanent fix. This, along with the gasket will keep the plug from coming loose.

The Motorcraft wire harness fit exactly perfect. The area under the valve covers is tight. You want to buy a wire harness that is made to fit exact - thats why I go with the Motorcraft.

Riff Raff prices, speed of delivery, and quality make it the best place to buy in my book.
