I would think the screen is to catch any charcoal that may work its way up from the evap canister. No screen will work fine till debris make its way to the solenoid.

My aftermarket coil doesn’t have a screen.

make sure you seal around the new coil so all of the air passes through it instead of bypassing it. Also make sure the evap housing is tight and sealed up. I used 3m strip caulk.
