I ran a Green drop-in filter in my previous ZL1 and now run one in my CT5-V Blackwing.
Never had any problems. You probably won’t notice any difference between the paper OEM and the Green.
I did remove the rain/snow blocker on my ZL1 which provides a more direct path for the air to enter the stock air box. Removal doesn’t provide any more boost but it seemed to build boost a little faster which gave my ZL1 a little more grunt in the lower rpms.
