The 225/210 hp 1.8T engines as fitted in the MK1 Audi TT, Seat Leon Cupra R and Audi S3 have an organic rubber hose on the intake manifold that feeds the brake vacuum system. This hose is prone to failure leading not only to a loss of engine power but also brake efficiency. The OEM replacement is only available with the hard pipes included, which incurs considerable unnecessary expense. As a cost-effective replacement or a precautionary replacement to avoid the potential failure we produce this silicone re-inforced hose. Please be aware that these hoses were patterned from right-hand drive vehicles. Whilst we believe these to be correct for left-hand drive vehicles we suggest that you visually check their suitability, as replacement items, with those fitted to your own vehicle, before attempting installation.
