The HKS GT II Wastegates are the latest in wastegate technology. They feature a lower body cast from stainless steel and an anodized purple upper case machined from billet aluminum. The GT II Wastegates weighs approximately 2/3's the weight of the original GT Wastegate and are significantly smaller in height and width. Their compact size combined with the GT II's V-band inlet and outlet flanges allows for versatile mounting in tight spaces. --- GT II Wastegates also include additional wastegate springs which allow for different base boost level starting points. A special tool is also included which allows for the simple installation of the extra wastegate springs.
