First off i hate the term ECO-BOOST. Like everyone on the planet doesnt know a boosted small displacement motor will make more power and get better efficiency than a larger displacement one. Not exactly news there.

As a mechanic i like the KISS theory. I cannot imagine how expensive or how hard this motor is too work on. The 4.6/5.4 werent powerhouses and didnt get the best fuel mileage but they are super reliable and easy/cheap to work on.
