Hey guys and ladies. Im getting ready to replace the glow plugs in my 99 7.3L. Now I know that Im not supposed to buy Autolite glow plugs and the part numbers zd10/zd11 on the AutoZone website come up with an Autolite glow plug but it also states it is OEM Motorcraft. Are those the glow plugs Im supposed to buy for my truck? or is there a different brand for the glow plug? I just want the right part the first time. Thanks in advance

 

They should be Motorcraft ZD-11 Glow Plugs. No where should it say Autolite on the package.

Buy them from Clay if you can wait.

ZD-11, Motorcraft or Beru brand ONLY. I'd skip AZ and buy them on Ebay. Paid $55 shipped for my last set.
