Q: Will this diffuser noticeably improve aerodynamics on my Model Y?

Honestly, at a normal Model Y ride height the aero gain is limited. The car sits tall enough that ground effects are largely negated, so if pure efficiency is your goal you may not see significant numbers. This piece is primarily a visual and construction upgrade that carries the Ascension design language to the rear. Lowering the car is what unlocks more from any underbody aero.
