Grille-ing Me Softly: A 30-Minute Makeover Adventure
Color: Single Slat Gloss Black, Size: 2019-2022 G20, Color: Single Slat Gloss Black, Size: 2019-2022 G20
Installing this grille was a breeze! It took me about 30 minutes, even with a minor hiccup of having to uninstall it to add the front camera panel I initially forgot. The grille feels incredibly durable, made from plastic that matches the quality of the OEM version. Plus, it gives my car a fresh, youthful look. Highly recommend for a quick and stylish upgrade!

Excellent fit and finish for the money. Just buy them.
Size: For BMW E46 2002-2005, Size: For BMW E46 2002-2005
Perfect fit. These grilles were better quality than the price would suggest. Easy to install, not brittle, and fit very snug. I’m not sure why there are so many negative reviews for these. I was fairly rough with the first one I installed and it didn’t crack. They look great. For a purist with excess money lying around, sure, go with genuine BMW. For a daily driver, you’d never know the difference aside from the black finish. Save the money spent on these over the OEM BMW and use it for something else. Below need not be read unless you like long winded car resurrection stories... The back story on the car for those who might wanna talk trash about its condition: I bought this ‘01 330xi from a buddy who really beat the car up. I’ve had to replace the entire front end and am in the process of painting the car. I had to source a hood at my local pick ‘n pull due to low funds because I bought a new house recently. The hood I found at the parts yard was for an ‘04 e46 (post facelift). Hood fits just fine and the grilles are perfect. Don’t hesitate to buy!

e46 Sedan Black Kidney Grill: Good fit with a better attachment mechanism than stock!
Size: For BMW E46 1998-2001
These kidney grill replacements were for a e46 sedan (323i). They fit really well. They come with a different type of attachment mechanism than other types I've used in the past: These have 'posts' with a slight groove that you gently pry into place against the hood's mounting tabs. It's a solid holding mechanism - much better than the tab-types I've seen in the past. These do not wiggle around, and feel very solid once mounted. They DID require a bit of fitting with a dremel where the hood release latch is mounted to the hood. I had to cut back about half-an-inch of the inner 'shell' of the grill so it didn't interfere with the latch when you pull 'up' on it to release the hood. Based on having an e46 sedan for 16+ years, and having replaced the kidney grills several times, I'm quite fine with a little bit of modification for a good fit. I like these quite a bit better than other aftermarket types, and even the OEM BMW grills. The price is good, and mounting is solid. I liked them so much, I purchased a second set for my son's 323i right after putting them on one of my 323i's. I plan on getting a set for a 325Ci one that car needs replacements.

They fit super snug and the quality is way better than price suggests.
Size: For BMW E46 2002-2005
They came in wrapped very well in foam and bubble wrap. They felt sturdy and the matte finish was satisfactory. They needed quite some pressure to snap in but when they did you could tell they weren’t going anywhere. The fitment is perfect and it looks great. If the stubs in the car where the grille clips attach are in tact you shouldn’t have a problem. Don’t be discouraged by the negative reviews.
