Nice for the price
Size: For 2003-2006 E46 2-Door, Color: Glossy Black, Size: For 2003-2006 E46 2-Door, Color: Glossy Black
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

Not 99.9 %
Size: CA12290-Premium
Only 98% efficient. Says 99.9 in the ad. There is a huge difference between those two efficiencies.
