Is it necessary to clean the air inlet with "disassembly-free cleaning solution" for car maintenance in 4s shop?

Hello, is it necessary to clean the intake pipe with disposable leaves for the maintenance of 4S shop? If it is sprayed directly in the cylinder, it is not needed. If it is only sprayed outside, it can be properly cleaned, but it does not have to be done in a 4s shop. You can also repair it in an outside repair shop, which is a few hundred dollars cheaper than a 4S shop.
