The Air-Boss CR is an elevated billet intake plenum cover for the 2003-2007 5.9L common rail Cummins. It uses the space above the cylinder head to create about 30% more plenum area toward cylinders 4, 5 and 6, helping airflow distribution and EGTs on modified trucks, and keeps the factory intercooler pipe geometry and mounting hardware. Choose a grid heater delete block, extended studs to keep the stock grid heater, or the All Seasons kit with both.
