Hi. I have a 1.2 8v 2002 and just wanted to know whether the pipercross viper induction kit is any good as I have a standard pipercross induction kit and was wondering what the difference is between the two apart from the price? And also, are the viper kits specific to each car model as I have seen one advertised in my local paper that says it's a universal fitment and is only £70?
