For years Cummins has vented crank case gasses to the atmosphere. With the new 6.7L emissions systems they've switched to a CCV or Closed Crankcase Ventilation system. The CCV system dumps the crank case gasses into your turbo inlet post air filter which causes an oily buildup on the turbo compressor wheel. If crankcase blow-by is higher than normal these gasses can also coat the inside of the intercooler which lowers its efficiency.
The Open Breather Kit converts the closed system back to an open breather. This eliminates the oil buildup on the turbo compressor and maintains intercooler cleanliness. 90° vent hose encourages oil drain back and helps eliminate drips. This kit does retain the stock CCV filter.
