The Turbosmart Type 5 SmartPort 50 mm upgrade kit converts an existing Type 5 blow-off valve to the SmartPort specification and includes a black anodized 50 mm SmartPort trumpet and a red -17 to -14 inHg spring. The kit offers an easy, bolt-on upgrade path to Turbosmart's latest SmartPort hardware, improving response and venting characteristics while remaining compatible with existing Type 5 BOV installations.
