The ATP block-off kit seals the stock diverter valve on the Hyundai Genesis 2.0T turbo engine. The stock diverter valve can run the risk of tearing or rupturing under high boost resulting a leak. This kit allows the stock diverter valve to be properly removed and sealed. You are now free to run something proven like an HKS or Greddy blow off valve through the ATP blow off valve pipe kit.
