i'm sort of thinking its just there to cover the ugly stuff and cover the transition into the windshield.
i know dogbone doesn't run his, but he is car is trailer kept and only sees track days.
Plus without it you will be pulling unfiltered air into the cabin / HVAC. I decided to leave mine in place for filtration and to protect everything beneath it.
I have the burger tuning filters... I'll have to look carefully, but does the secondary cover cap anything else?
