Bought these for my OBS along with the valve cover gaskets and pigtails to convert to a single plug. OEM quality for sure, can't wait to get these bad boys installed!

Replace along with glow plugs, easy install, unexpected plus was installation fixed a small miss at about 1500 rpm, as the old passenger side harness came off in pieces. Great product.

Truck was throwing an intermittent p1316 code. Upon inspection, UVCH was loose and kept losing connection. Replaced them with these new OEM UVCH and new valve cover gaskets and the problem was fixed! The new harness seems to plug in much tighter and will hopefully eliminate this problem for the future.

Replaced both harnesses when GP's tested bad during a SXE turbo install. Previous owner had installed a Dorman UVCH on the driver side of the engine. Side by side comparison between the Dorman and Ford, there was no contest or question that the Ford was far superior.

Quality product and great support from RiffRaff.

Best quality selection of Motorcraft.

Great fit. Especially
the glow plug connectors.
Highly recommended.

Riffraff offers the best pricing on quality factory parts. Fast shipping and great service. Great business, I look forward to doing business again in the future.

Ford motorcraft parts at the best pricing I could find. They shipped within 2 hours of when I ordered. Can't ask for more.

Had a SES light with two open injector circuits resulting in a "dead miss" on a couple of cylinders all of a sudden. Ordered harnesses for both sides and they arrived the next day! Replaced the parts which fixed the SES and engine miss but also fixed some issues I had had with romping on cold start and after towing (hot). Engine is smooth, smooth again!
