depends how much u wana blow , believe the carbonios spose to be good , has long pipe , to take away from engine etc,
provide u have decent shielding from heat , plenty of cold airfeed it would gain power , but to compare against a panel im not sure,
some of the big boys on here went for panel filters apos to induction , hence why i went for panel, these guys have researched into these things for a long time ,
up to you really , if u bought one and wanted the other u could always sell on im sure people would snap the panel filter up no probs
