love it.
This filter fits a 2008 Lexus RX400h perfectly and gives the fresh, clean air. I recommend it.

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.
