Engines can be pretty durable. Your's is still working. If any harm was done, it's already done. Can't worry about that now. Look ahead. Remove your Intake from the air box to the throttle body. Clean everything as best as you can. Also, clean the Mass Air Flow sensor.
Re-Assemble with Tornado
your TC should run better and get better gas mileage now! My guess is the old filter had so much resistance that it tore. As for grime I would clean the intake as well as you can. If there is a lot of grime way up it I would be somewhat concerned about engine wear. If you have been driving in a not too dusty environment then probably not that much grit has gone thru the engine. IMO the biggest issue would be worn piston rings which could cause oil burning and loss of compression. It looks somewhat dark, is that from dirt? I wouldn't swap out the intake hose but might remove it and throughly wash it if that is not too difficult.
