I'm thinking WR7DC+, the resistor version that was originally fitted. 7900 is the current Bosch part number, with nickel plated shell.

Call one of our vendors for them, add to the rest of your parts order. Business environment is a little challenging right now. Help our brothers (and sisters) out by shopping in the family.

What those guys said, you will know you will get the real deal and not some knockoff from Amazon/Ebay.

I believe the NGK BR8ES is another alternative. If in a hurry, you can probably source those at your local auto parts store (Advance usually has that specific plug). Of course, that doesn't help our Brothers in Arms out though. Heat ranges in NGK work opposite of Bosch - in Bosch a higher number is a hotter plug and in NGK a lower number is a hotter plug. You do need to have the "R" for Resistor in the plug number with either brand for the 928.
