Save your money!
Size: For 1998-2001 E46 Sedan 4-Door, Color: Chrome
Complete waste of money. I bought these specifically for my 2001 BMW 330i sedan and the fitment was terrible. Tabs don’t align, quality is poor and both grilles fall straight off. Definitely would not recommend!

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
