Banks Billet Grid Heater Delete Kit 2007.5-2012 6.7L Dodge Ram Cummins If you've ever pulled your intake manifold to see the design of the factory grid heater, you'd know the importance of eliminating it. The stock intake plenum features a built-in grid heater that severely restricts airflow at the point it matters most. This replacement intake plenum from Banks is designed to work in conjunction with their Monster-Ram intake manifold to optimize airflow for improved power, turbo spool up, and reduced temperatures.
