The original hose is a hardline made out of some type of plastic with rubber joiners. It's approximately 2-3mm inside diameter, Silicon hose will do the job. Get the correct size to fit snugly on the ECU and manifold fittings. Can't remember whether mine is 2mm or 3mm.91 Modded 3B

on cars like the corrado it had to be a certain length too. 1000mm of 4mm brade wrapped pipe on one of them
not sure on s2. probly worth mearuring first. use an old rear diff vac hose and cut it may be best betComment
