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

Not much one can say about motorcraft parts. They work as well as those that came in the truck. What is amazing is the SERVICE. This is my second order from Riffraff and they were shipped the same day they received the order!!!

Good product. Always buy from riffraff

After 20 years I had one stock glow plug go bad. Threw a code in CA emission truck. I replaced gaskets, inside valve cover wires and all 4 glow plugs on that bank. The numbers on these glow plugs were EXACT match to what was removed. They went right in per instructions on web page. I cleared the SES code and am back up and running with no code. Hope these last as long as the ones they replaced. Approximately 1/2 the price as dealer. Got them within a week even during Covid shutdown.

I've bought 2 sets and have had good results both times.

Price was good
Shipping perfect
Price was really good
Was packaged in Ford package so you know not a knock off
Got all valve cover gaskets and harness and glow plug relay
Best of all Clay responds immediately if you have questions or need help
He even called me up to help answer my questions
That worth a ten in my book
Great company
