The Turbosmart Type 5 SmartPort 50 mm upgrade kit in silver provides a straightforward conversion for existing Type 5 blow-off valves, including a clear-anodized 50 mm SmartPort trumpet and a red -17 to -14 inHg spring. Intended as a simple upgrade, the kit brings Turbosmart's latest SmartPort spec to older Type 5 BOVs for improved response and more consistent venting without replacing the entire valve assembly.
