Airbox issues

[InkedMuttley]

Okay was going to attempt to service my car the other day until it started to piss it down just managed to change the air filter upon removing the airbox lid/bottom water started pissing out of it and about 3" up my air filter was absolutely soaked dried the bottom of the airbox and replaced the filter with a nice new one went for a spin and was getting an almost induction sound wondering what was wrong with it so had a friend take a butchers and the airbox lid is screwed it's sucking in shitloads of air and debris now seeing as Peugeot are the only ones that stock the new airbox at £58 + VAT I've decided induction is the only way to go so can SOMEBODY please tell me how they managed to fit their induction kit?
