CEL came on after I changed the air filter 2 weeks ago. It was a K&N high flow one that was red. Codes were P0171, P1170, C1201.
I reclamped the air filter box 3 days ago, double checking that the tabs on the bottom lined up well, and figured itd go away.
It didn't so today I did some inspecting and found a golf ball sized hole in the resonator thats attached to the bottom of the intake, after the air filter box. About parallel to the outlet that goes to the cabin sound generator tube.

It must have happened during my first install, when I was moving pieces around. I dont see how, but the CEL coincided with the first attempt at install so it must have happened then
I'm gonna buy a replacement resonator and put it in but
my question is, how bad is driving around with a golf ball sized hole in your intake?
I haven't driven through any particularly dusty areas but I've probably driven 200 miles or so on highways and cities. Its on the back of the resonator, the side not visible when looking at your engine from the hood. Is there anything preventative I should do to help mitigate damage? Or is the damage done and Ill find out in a few days/months/years when my engine needs rebuilding prematurely.
