HKS GTII Universal 50mm Wastegate 14005-AK002
HKS GT wastegate has big engine displacement and high supercharging pressure for smaller and lighter designs. The installation with the V band makes it easier for maintenance.
2 types of valve diameter are available (60mm, 50mm) for stable control over boost for any size turbocharger. There are 4 wastegate springs for 60mm and 3 for 50mm (2 are already loaded for both products), therefore, it's possible to change from a wide range of boost pressure settings.
