Replacing Air Filter

Very, very novice question, but I’d rather ask than break something and be sorry later.

So just bought 2 K&N air filters, seems pretty simple but I want to ensure I’m doing everything correctly. So I see three screws on the actual air filter housing, there’s also the part of the intake that connects to the housing, then lastly the plastic portion in the front that can easily be removed to separate that part from the housing.

Is it that easy? How fragile are these plastic parts? More or less just need someone to walk me through the process.
