There is a thread in this forum on how to replace engine air filter. I took their advise and replaced the engine air filters for my 2007 G450 today. In the process, I took pictures to show how I did it. Hopefully, the pictures will make it easier to understand. It is an easy job to do.

Step 1: Open Engine Cover.

Step 2: Remove air hoses (3 red circles) and a stabilizer bar (1 red box). A 14MM star socket is needed to remove the 4 bolts on the stabilizer bar.

Step 3: Push back a metal wire clip (in red circle) on the back of the air filter housing which is already removed in this picture.

Step 4: Remove the air filter housing.

Step 5: Open air filter housings. There are two of them. Need a T-30 star bit to open the screws in red circles.

Step 6: Install two air filters into the housings.

Reverse the steps above to put back everything.

While I am doing this, I also changed the cabin air filter. it is also an easy job. Following is an instruction from part vendor.

This looks a lot easier than GL320. And filters look a bit smaller also.

I know it is older thread but thanks for the tips. I had a E350 for years and the similarities under the hood is cool. That car was the easiest to change oil in and air filters were also pretty easy. I just bought my 2011 GL450 and it looks like both oil and air will be done soon so that I know where I am with this. Maybe even the trans fluid one day once I get a bit more miles under my belt.
