Great a fit, easy to Install
Size: For 2002-2006 E46 3-Series Sedan, Color: Chrome
Fit perfectly. To install, slider the bottom in first, then press the top in. It will snap into place and fit snuggly. Recommend.
I have an e46 2024 330i.

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.
