Review on Econoline Excursion 3W7Z12029AA 3W7Z 12029 AA 1L2Z 12029 AA by Gopal Baltimore

I bought 10 CoP packs for my 1999 Ford E450 V10 6.8 liter Triton engine which powers my class -C-RV is They ran about 600 miles and the engine died again. The OBD2 codes indicated that cylinders 1, 2 and 6 were constantly misfiring. Now you might be thinking they must have lasted 60,000 miles or so. No! After driving less than 4,000 miles and driving half the country I had to buy 3 replacement CoP packs for $60 each and renovate the Wallmart campground to replace them. I have signs of a couple more CoP packs failing, cylinders 7 and 10. These are rubbish and I should have used either OEM or quality packs. Replacing these packages on a V10 Triton engine is very difficult, time consuming and requires removing a lot of material from the engine to get to the CoP packages. Save yourself the pain and suffering and get quality parts instead of this market junk. Update: I've lost four more CoPs since writing this review. That adds up to a total of 7 out of 10 CoPs that have gone bad since I got them. They have less than 10,000 total mileage. It's just junk and their burnout has nothing to do with the on-board computer (the power management module that controls all of the engine's electrics) as I replaced it before the last 4 CoPs burned out .
