Have you already installed this on your car? This part doesn't smell right to me.
The website doesn't say what polymer they're using to build the part, but judging from the flexibility shown in the video, it's likely thermoplastic polyurethane (TPU). They have you heat it up to (1) expand the diameter of the two holes, and (2) make the polymer more flexible, likely getting close to the glass transition temperature (Tg) of the polymer, making it much softer.
What concerns me is the underhood temperature possibly exceeding TPU's Tg of 65 C (150 F). I don't have any numbers on under-hood temps, but 150 F seems plausible on a hot summer day. Keep an eye on these and make sure they aren't deforming.
