Review on ACDelco CF3345C Professional Cabin Filter by Tim Wilske

So far, so good. I ordered another product that said it fit, but it didn't. This ACDelco filter is great for the gs350 and the car keeps the air inside clean. It may not slide at first, but just make sure the mount, which is part of the cradle frame in the car itself, fits snugly in one of the folds. And then he falls right in. The problem I had with another manufacturer (NOT ACDelco) was that the air cleaner itself had a hard plastic piece that ran perpendicular to the hard plastic frame of the intake bracket. So they collided and he didn't fall. ACDelco does not have this problem. Hope this helps other do-it-yourself installers.
