MAS Set of 10 Ignition Coils Pack DG508 & Motorcraft Platinum Spark Plugs SP479 Compatible with Ford E350 E450 F250 F350 F450 F550 Econoline Super Duty F53 6.8L V10 DG457 3W7Z-12029-AA

This package was the Big kahuna to get the job done. It's all motorcraft that's what the motor takes anyway being that it is ford. My 2001 6.8 l was happy and fired up without a sputter. You get your money's worth with this package. Course having all this functioning is important for fuel mileage and reliability of your engine as a whole. Don't let those 10 cylinders lag behind. Everything fit as it should and secured without any issues. Due to the spark plug hole design recommend purchasing a blower if you don't already have one either electronic or air powered to remove all the crap that is accumulated in the holes which house your spark plugs.

Came in fast and went in as easy as a Ford Modular engine will allow you to. Fixed the miss I had on my 6.8 V-10 on cylinder #5 and smoothed out the idle and provided more pickup. Just make sure you gap your plugs per manufacturer recommendation.

Excelente producto,gracias

I was worried about running the aftermarket coils after hearing that they don't last. So far I've put around 26k miles on the truck since installing them and they are still working good. I keep a couple of the stock coils in my glove box in case one of these fails. Most of them installed easily, the back one on the passenger side is kinda hard to get at.

Very good for the price

Good plugs. Good quality, good coil packs solve my misfire .

Works great so far

Isn't working properly just 4 months, is better for the factory
