How to change air filters on 2010 e350 coupe
Hello
I am looking for advice and assistance on how to change the air filters on my 2010 e350 coupe. I just ordered a set of K&N air filters 33-2181, and need to know on how to get the old out and the new ones in.
Anyone have an idea on how to do this
thanks

Wow 141 reads and no replies.
Well today I received my 2 K&N filters purchased from advance auto for $71.68 shipped to Blaine Wa. In Canada these are around $100 a piece, so I saved about $130 by getting them myself.
Now comes the tough part how to change them and after reading hundreds of posts all over the world no one appears to have posted this for a 2010 e350 engine.
From trial and error I learned by pulling from the very front of the engine cover there are two prongs that fit into rubber suction cup items. This piece is hinged and as you lift up it exposes the rear attachments which consist of a center plug and two metal clip types that pull off.
Once this is removed I put it aside and then pulled of the left and right hoses that go to the air system which is the main unit you see on top of the engine, I then used a plastic spatula to pull off the flat end by the rad and put these two hoses aside.
Now comes the main unit which sits on 4 rubber bushings on the side and then fits over the air intake at the rear and has a spring clamp holding it down. Before you do anything there is a 1" rubber hose at the front you must pull back then unclamp the rear hold down by pushing it towards the firewall. Now lifting from the front of the unit pull up and back and off the air intake.
You are now in possession of one of the largest air intakes I have seen. Carefully turn it over on a large blanket and you will see there is a left and right air intake. Using a torx screwdriver evenly un-do all 4 screws so that you do not bend the plastic lid.
Remove the old air cleaner and push in the new air cleaner carefully seating it completely around the housing. Replace the housing and carefully screw down all 4 corners equally so as to close the gap evenly otherwise one of the corners will not fit correctly.
Once this is done on all 4 corners there should be no gap between the 2 plastic pieces where you tighten the torx screws down.
Now with approved Mercedes rubber lubricant, you have to lubricate the large 4" seal that goes over the intake and the 4 rubber stand offs which support the housing.
Tilting the housing down place the air cleaner over the intake so that it slides over the neck then seat the remainder of clamps over the rubber standoffs. If you lubricated everything correctly this will slip and click in place. Now re-attach the rear spring clamp and the 1" hose on the front of the air cleaner.
You can now re-attach the front cover by clipping the rear in place first then snapping the front down, make sure that you also snap the hinge portion correct into place and everything should look perfect flat.
To re-attach the air intake hoses place the flat rad side in first then the round side to the air intake unit pushing it firmly until it properly snaps into place. This piece has a tendency to appear to be in place but is not.
Attach stickers on left and right rad mounts and K&N decal in center support, wipe clean down and you are ready to go.
Now as for people hesitant about these filters I have used them on new vehicles for the last 35 years and never had a problem what so ever. I was concerned over people mentioning problems with MAF or known as mass air flow sensor and researched this with K&N and to my surprise if there is any problem K&N will rectify the problem with your dealer without you have attempt to resolve the problem.

If you are skeptical about doing this, it was relatively easy and took about 1 hour including clean up and detailing the engine afterwards.
