Tl;dr - the ‘eBay’ clone frunk hooks are pretty much identical to the OEM Tesla ones.
For reasons too complicated to explain, I have two sets of frunk hooks - a pair of the cheap clones from eBay and an OEM Tesla pair. Here is a comparison:
Shape and fit: the two are pretty much identical. The only difference (other than the Tesla manufacturer markings) is the clones have a slight indentation at the top of the ‘hook’ part (see picture 3). The Tesla ‘hooks’ fits perfectly onto the clone ‘bases’ and vice versa.
Materials: The Tesla ones are labelled >PP-GF20<, which Google tells me is Polypropylene with 20% glass fibre. The clone ones don’t have any markings (other than L and R), but they seem to be invariably advertised as being made from ABS.
Colour/texture: the difference in materials probably accounts for a slight difference in colour (the clone ones are a bit more charcoal) and texture (the Tesla ones are a bit shinier). The Tesla ones match (colour and texture) the Frunk liner a bit better, presumably as they are made from the same or similar material? The mouldings on the Tesla ones are also a bit sharper (e.g. see the three bar logo in the first picture).
Operation: The Tesla ones are a bit ‘stiffer’ to operate i.e. they need a bit more effort to open/close. I’m not sure if this is a good or bad thing - they seem to latch open/closed a bit more ‘positively’.
In summary, the clone frunk hooks are pretty much identical to the Tesla ones. Here are some photos - the Tesla ones are on the left.
I have fitted the OEM Tesla ones to my M3.
Appreciate much discussion on these, but just a quick share on a great pair of frunk hooks I’ve just fitted, for the paltry sum of £5.55 delivered!!! I was tired of my 2020 model having holes, so took a chance on these cheap eBay ones from China. Only took 15 days to arrive and absolutely brilliant for the money, good match, good quality, and highly recommended!
