I work at a SEAT dealership, and a bloke came in after fitting one of these himself (one made for Seats). It ended out that he needed his original cool air intake system replaced, his ECU re-mapped, and on top of that he had to pay labour charge. It wasn't good for those who dont have a rather fat wallet as 'Seat Tech' were involved. I dont see why he felt the need to fit one when he already had 180BHP to play with to be honest These things are just more hassle then they're worth I'm afraid.
