I don't know if Toyota has a couple different modals of bug shield or some dealers are selling non Toyota ones because mine is stamped Toyota on the bottom and uses no hooks tape or anything. The one I have does not cause any damage, just some inserts and screws on the inside of the hood.
The one i saw in the dealers lot (with maybe 5 clips resting against the hood top with a thin plastic adhsive buffer) was on a brand new 08 or 09. I saw it when i was scouting out a replacement for 2000 that was pending frame buy back.
...don't know it its is one they just started using this year or if they have multiple styles available.
