Thanks for this confirmation. My 16 went boom (#2 cylinder, blown head gasket). I don't want another used engine, especially since a new Ford Crate engine is only $1k or so more. My mechanic will charge me the same for labor, new or used.It's been a while since you posted, but I can confirm, that 2018 engine work in the 2015 car, as my '15 car has swapped '18 engine. There were literally nothing to adjust, just plug and play.
