right then well at risk of sounding like a right noob ive got a cai kit for my car its not top notch but i got it cheap of a mate who had it fitted to his octavia now the question is how is the best way to fit it i looked and can see how it routes but do i have to take the battery out to get the pipe down to bumper then how do i put the filter on is it easier underneath or take the bumper off i dont really want to take bumper off as its a faff so just wondering how you guys fitted yours ....... cheers

Easier to take the battery out but you don't have to. Also easier to fit the filter to the pipe via behind the wheel arch trim!
