Hi I'm wanting to fit an s2000 filter to my 1.9tdi as my friend has just fitted one to his and has gave him the cooooo coo noise which I'm after. I currently have a pipercriss panel fitted and I'm booked in for a custom map next week so would like to know which one to leave on for that. He said he hasn't noticed no down sides to fitting it as I'm lead to believe that cones suck too much heat in. What's people's thoughts experience with cones filters these are basically a cone paper filter. I so want the cooooo noise as I expected this when I fitted my full.stainless and now I know this will give me it as my mates car is exactly same species as mine.
