One of the best on the market are made by Beru in Germany. If you go to your Ford dealer, that's what you're going to get anyway - just in a Motorcraft box. Lasts one I bought, they were just as cheap at the Ford dealer as anywhere else.

1987 6.9 and 84-94 7.3 diesels use:

Beru ZD9, Delphi HDS307, Champion CH84, Lucas/Delphi DS092A, WAP 84

Specs:
V1 = 12 V2 = 5 A = 7.4 T3 = <50@ 5V T4 = <50@ 5V , 10mm X 1.00

V1 = vehicle system voltage.
V2 = voltage marked on glow plug.
A = current at working temp.
V3 = preheat voltage (system)
T3 = time to C degrees working temp at V3 (seconds)
V4 = voltage for testing separately
T4 = time to working temp at V4 (seconds).

Before trying to remove glo-plugs, soak around threads with good penetrant with engine a little warm. when plug breaks loose, work back & forth to free tube in head. more spray lube if necessary.

Champion = THE worst!

Motorcraft/Beru = the BEST!

End of st ory.

JD knows what he's talking about. I had the number of the ones I put in mine in the pocket of my bibs,but I think I finally tossed it. I can tell you from years of experience though,make sure you change them ALL. Somehow the sensor detects a change in the amperage draw or something if even one is a little different. I struggled with mine for YEARS just changing the ones that were bad every year. Finally changed the whole set at one time a year ago and it was like getting a new truck.
