Simple question about cleaning the throttle body on this '89 190E 2.6. The instructions say to remove the air boot that connects to the throttle body, use a shop rag to absorb excess product, then start spraying while playing with the butterfly valve. This car seems to be different though. Can I do the procedure by only taking the cleaner cover off, and not the entire assembly? Is this the throttle body (see pictures below) or is it hidden somewhere under the actual air filter assembly?

The valve pushes in kinda sideways:
