The German Wagner Tuning offers a wide range of after-market performance parts, for many different brands. The products are characterized by very good quality and clear assembly instructions. The after-sales service is also very good.
Winparts supplies intercoolers and downpipes from Wagner Tuning. Wagner tuning distinguishes between 'Performance' and 'Competition'. The Performance parts are a (strong) improvement of original parts. The Competition products are a further development here, with features that are also usable on the circuit. The Performance parts are plug-and-play in most cases, while at the Competition parts something needs to be adjusted. This appears from the manual.
