Ignition Coil MOTORCRAFT DG-521. New in original, sealed bag. Don't buy "non Motorcraft" coil's.. The fake parts are proven unreliable. Bought this for my 2010 Explorer V8 as a spare. Sold the truck and never used it. Cleaning out my shop of extra parts, so you will get a good deal here. This coil pack generally used on all Ford Triton (3 valve overhead cam) 4.6L & 5.4L engines
