Review on MAS Set of 10 Ignition Coils Pack for Ford Super Duty E350 E450 F250 F350 F450 F550 F53 Excursion 6.8L V10 - Compatible Replacement For 3W7Z-12029-AA DG508 by Kwesi Delgado

I am writing this review after 6 months of use. I bought them in July and installed them on a 2001 Ford Tour with a 6.8 liter V10 engine. For the price they were honestly really good for my application. I bought the Excursion with a heavy slip knowing it would need spark plugs and coils. I've got almost 6000 miles on them and they haven't failed yet. In my opinion a great price. Installation Tips: Clean the area around old spark plugs before removing them. After removing them, vacuum the head opening with a vacuum cleaner to remove any dirt and grime that may have gotten inside. I used an old 1/2" LB line with tubing on one end and a factory vacuum on the other end. Rest assured. Torque the spark plugs to spec with an anti-seize coating, and not too tight or else if there is a risk of burning out the spark plug (common on these engines) use dielectric grease on the boots and connectors clean the coil power connectors with an electronic connector cleaner and apply some dielectric to them I would definitely buy them again .
