Need to replace a couple glow plugs, gonna do them all. What is the best glow plug? Motorcraft ZD11 or???

 

ZD11 are by Beru and sold by Motorcraft. They are recommended, I would use Bosch if available...they are OE on my MB Diesels.

 

Interesting on Bosch. 80033 is the part number for a Powerstroke.

 

Guess I should be more clear, I would prefer the OE spec ZD11 and that what is in my dually. I would have no problem with Bosch if the Beru units were not available.

 

OK, got it. ZD11s look plenty available.

What is the deal with ZD11B2? Are they better?

 

I am not sure, sorry.

Also, I would recommend buying them from Riffraff or Diesel Orings and picking up that HD glow relay while the system is apart. Two reasons. First to save cash on freight and second to buy the plugs from a known source.

 

The ZD-11 glow plugs are not being made and packaged individually anymore. There is likely old stock around, but the ZD-11s are now sold in 2-packs.

 

And to support quality, helpful vendors. I have nothing but good things to say about both of these companies.

 

yup. the only difference between ZD-11 and ZD-11B2 is one per pack and 2 in the pack with the B2's
