obviously its the viper all the way but the panel filter costs 1/10 of what the viper does, anyone got any strong reasons why i wuld want the viper? on my old clio i had a panel filter, a hole cut in the front of the o/e airbox with a piece of ducting leading to the side of the radiator, surely the advantages of the veiper over this sytem arent worth 180+ quid?
