Review on Brand Motorcraft ZD 11 F4TZ 12A342 BA 1995 2003 by Fuzzhead Nelson

About 80% of buyers do it themselves like I do, but if a glow plug fails, the seller will ask for a mechanic's letter or documentation proving the glow plug failed. The price at the local store near me is $120. / hour when glow plugs are only $77 at the exchange rate. I'm a Red Seal Electrician in Canada and I'm willing to prove it with a multimeter and send back the bad ones too. I only have 5 bad ones and one completely dead. I installed them in October and now it's January so it's only been 3 months and I must have gotten a bad set of spark plugs. Better buy from someone else
