Actually,
There are four metal screws that attach four metal clips through pre-drilled locations on the deflector.

These clips slide onto the leading edge of the hood and appear to be a very snug fit.

If you look closely above, there are four 1.5" pieces of heavy duty velcro, that are oriented vertically every ~10" across the top of the grill. Mine were already attached to the deflector so all you have to do is remove the protective film and apply pressure to each tape for the deflector to maintain a very firm grip on the hood. The only other applications we made use of the six contact pads for potential vibration/wind gust mitigators at the corners.

Special THANKS to
@OwnerCS for providing some pics of his installation. His directions were in Russian...
I really don't know how I feel about the LEXUS advertisement on the deflector but I imagine a heat gun and a plastic scraper will make short work of it...
Cheers mates,
