I'm afraid the engine bay is a bit of a letdown. Gen 3 Coyotes have this huge engine cover that hides almost everything. Earlier generations used intake and coil covers to dress things up. I'm not sure if those items will work on the Gen 3's.
As everyone already knows the engine is huge. It make some maintenance issues a bit problematic. ie: clutch master cylinder access. Gen 3's also present some new tuning issues that traditionalists don't have.
