Never know if you get Genuine parts from Amazon. I'm happy to purchase from RiffRaff as I know they provide genuine. These worked great and of course were Genuine OEM.

Great product. Why risk your diesel with anything other that Motocraft.

Wish I had bought these from Riff Raff last time! 2 years ago, I thought I'd save some money buying "genuine motorcraft" from an ebay seller for a surprisingly low price. Those 8 glowplugs came in ligit looking individual motorcraft packages and were marked identically to those I was pulling out of my 2003 7.3l. I found out the hard way that some parts savings can really haunt you ... less than 2 years later, all 8 glowplugs read open AND WORSE THAN THAT, all 8 had swollen to the point where they were nearly impossible to remove! 2 even broke off (dropping their tip into their cylinder). I wasted many many hours getting those fake glow plugs (and tips) out of my motor. REALLY wish I had bought them from Clay in the first place. His prices are always good and his parts are always real.

The best you can buy! Made a big difference with cold starts.

Start like a brand new truck But 1 480000 miles But 1 480000 miles

Riffraff continues to provide quality OEM parts at a great price. Shipping was great as always, would absolutely recommend Riffraff for any diesel owner.

Only go with OEM

Great. I used to have to cycle my plugs 7-10 times before my truck would start and now it starts on the first cycle everytime. Worth the buy. Worth the money.

My 2001 7.3 was giving hard starts even when the weather was warm. I ordered new plugs new harness and new valve cover gasket. Problem solved. Its been in arrowhead a 32 deg and started right up. Shipping was quick also. Thanks Riff Raff
