  • 1 x HPL-1001 - 5/8" ID coolant barb cap
  • 2014+ (C7) Chevrolet Corvette
Installation Note
  • This cap is a sub-component in the C7 Corvette factory oil cooler deletion kit (Part # HPL-1003-KIT). Capping only the radiator hose-barb alone will not delete the factory oil cooler and will leak coolant from the factory cooler.
