Not an exact equivalent to the original two piece design
Size: For 1998-2001 E46 Sedan 4-Door, Color: Chrome
Not an exact equivalent to the original two piece design. It won't snap in place as a direct replacement and required some glue. Not sure how long that will last.

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
