Quoting strokin4dr:
I think they look like a good quality part for what it is. That said, I'm pretty some they are knockoffs.
Lots of fake HKS parts out there, bovs, cams gears, etc. Even the boxes are nice copies.
Still, it's just a cover with no moving parts. It should be fine. /ubbthreads/images/graemlins/dunno.gif
like i said almost 20k miles on mine and no cracks or anything. its clear and does what it needs to do. keep crap out and let me see in. even if its a knockoff it looks really good and is of nice quality. im more then happy with mine. i take the cover off every 5k or so miles to clean the inside as it gets dirty.
