So i had some glow plugs go bad and on an internet search i found advance auto parts now sells the motorcraft zd9 glow plugs. the price was reasonable $12.09 per plug. most stores have them in stock, they do free shipping on orders over $75, and if you do a search for "advanced auto parts promo codes" you can get another 30% to 40% off . my 2 plugs ended up costing me $18 with tax. they also have controllers for $85 "part # gpr8". hope this helps anyone looking for parts.

 

Sounds like a good buy. Might be time to buy ahead because when you need them, they are never on sale.
