Economical, easy to install, and does the job!
Style: BE-182 1-Pack
First, depending on your car model, replacing your cabin air filter is VERY easy.
With that out of the way, the shop wanted to charge almost 65 dollars to replace my cabin air filter. Decided to just buy one and do it myself. The only downside of waiting is that the air inside the car is not as fresh/clean when you're running your air. Anyways, you can usually get these kinds of filters between 20-45 dollars from auto part shops depending on the brand and features. I've used this brand and filter for the past 3 replacements on my car and they last just as long and filter just as well from my experience. No issues installing, and does in fact do a good job of filtering outside odors.
Highly recommended for the price!

Fits 2005 325xi
Size: 2002-2005 E46
Snapped perfectly into place. Zero play with the fit and hood hinge still just as accessible as oe grille. No trimming required. If you’re sick of snapping your grille back in every time you lift the hood, buy it!
I also have the colored grill inserts and they snap on perfectly with no play.

Fit is perfect and these have a very nice glossy finish
Size: 2002-2005 E46
Fit is perfect and these have a very nice glossy finish, which looks much better than the matte finish. As others have said, the driver's side grill lacks a cut out where the hood latch pull handle swings out when you need to lift the hood (compare the driver's side grill with the existing grill to see location and size of the cut out). I was able to cut an opening within 10 minutes and I haven't had any problems opening the hood since the installation.

Nice Finish, Decent Fit
Size: 2002-2005 E46
The fitment isn't perfect like the OEM grilles, but overall I was satisfied. These are just slightly smaller than the originals so there is a little play once installed. No need to modify the LH side grille for clearance to the hood latch though as other reviews mention. It looks like the design has been revised to address that problem. I was impressed with the paint finish and there weren't any noticeable blemishes like dust or dirt in the paint. These are probably the best and cheapest gloss black kidney grilles for E46 that are currently available. OEM grilles w/ gloss black are basically discontinued so we're all stuck with aftermarket if you want the gloss black shadowline look.

loose fitment
Size: 2002-2005 E46
I guess it's a hit or miss with this. You either get perfect fitment or poor fitment like I did, after the install it's very loose.
