My first post here. I have a question about the 2020 C300 engine air filter change. I have the Cabriolet but it's the same as the coup. I think you refer to it as w205 or perhaps A205 for the Cabriolet.
I want to change the engine air filter, bought one from the dealer. I've looked at about 50 YouTube videos but none are the same car. I'd appreciate some advice.

There are 4 torque screws that I can see, I've loosened them all. Also took off a clip between 2 sections of the air intake. When I try and lift the top cover, it hardly moves. I can't see what's holding it down. Does anyone have a source or some advice?

Thank you

 

So it is different on the cabriolet? Did you see this video linked:

 

Here are more:

 

I got question related to the topic- are the K&N ones in any way better than OEM ones? And what would be the benefit?

 

K&N are likely performance filters, which allows more air in which then means it will filter less. Do you want more performance or better filtration? The choice is yours.
