I've bought a cone filter!! What size is the standard pipe once the standard box is off? And do you have to take battery out to get box out ?
What model of Megane do you have? I have a 250. I removed the battery casing to get the screws a little easier. But didn't have to remove the battery itself. I didn't remove the whole airbox though. What cone did you buy? I thibk the size is around 70mm in diameter. Someone may correct me though!
