If you've seen a Coyote 5.0 in an '11-'12 Mustang, you'll see the same thing in a '13. Its beauty is more than skin deep, however. Yes, lurking inside the engine are a few hardware changes that stack up to an additional 8 horsepower. Those gains come mainly from reduced windage via deleting the piston oil squirters, as well as some new rings and a phosphorous coating on the pistons. Stack up those little changes and you get some power. It's not just a few magic numbers in the calibration that created that power.
