Nice for the price

Overall, super happy with it. Didn't expect much since a genuine one is 2-3x the price, but it fits decently (could be better) and isnt super flimsy. It isn't perfect, but its the best youre going to get without buying a genuine OEM one.

It’s just an air filter
Size: CA12290-Premium
It’s exactly how it’s pictured. Not sure what else to say it’s an air filter. I guess it’s doing its job
