Made from the rear spoiler of a 90's Subaru Legacy wagon.

This is the second Insight I fabricated this same kind of grill block for. It looks so OEM it's almost invisible, and Insights without one look funny to me now.

Lots of people ar telling me that they cant really see the différence until they're up close.

I saw this Kia Soul in a parking lot; I am pretty sure that is OEM:

The lower grill was only made about half open; there were holes on the front, but flat plastic in the back. I noticed a few new cars like that.

Openable (powered by 2x powerlock motors) - smaller for intercooler, larger for radiator.

Older version :

Newer version. In winter, I block off the right side with a flat piece ( with matching teeth )

Is the top blocked as well ? You might get better results if you block the top instead. One of the members here did some flow testing on a car much the same as yours. ( I think his is a Chevy Malibu.The grille design looks identical to your car. )
The testing showed some detached flow right at the hoodline.
