I'm no expert but I have had as many as three Ford vans running at a time in my business. I have had to replace coil packs often. Every time it was an O.E. coilpack (motorcraft) that needed replacing. More than one mechanic has told me that Motorcraft was the only brand worth buying but they are not cheap as you have noted. Two of the defective packs I had to replace had only 70,000 mi. on them. I have not have any of the aftermarket packs fail but none of the new ones have been on the vans more than 40,000 mi. I bought my last set at rockauto and they are manufactured by United Ignition Wire and cost around $20.00 each. That is less than half of Motorcraft. I cannot say they will last as long or longer than Motorcraft but so far, they have gone 40,000 mi.+ with no failures at half the cost.
