GDP Air-Boss CR Intake Plenum Cover 03-07 Dodge 5.9L Cummins 0307ABIPEGT's running too high? Can't use all of the fuel you have available? The GDP Air Boss intake plate gives the largest flow increase possible short of milling the cast plenum off the head and installing a fabricated intake plenum. The Air Boss plenum isn't just a replacement flat aluminum plate as seen in other designs. The Air Boss is a true, elevated plate designed to flow as much air as possible to cylinders 4, 5, and 6. We've all have seen the head
EGT's running too high? Can't use all of the fuel you have available? The GDP Air-Boss intake plate gives the largest flow increase possible short of milling the cast plenum off the head and installing a fabricated intake plenum. The Air-Boss plenum isn't just a replacement flat aluminum plate as seen in other designs. The Air-Boss is a true, elevated plate designed to flow as much air as possible to cylinders 4, 5, and 6. We've all have seen the head gasket failures between the hottest running #5 and #6 cylinders. With this plate design GDP opened up the plenum area to the starving rear cylinder by a full 30%. By increasing airflow to the rear cylinders, it reduces EGT's and allow you to run even higher fueling levels.
The Air-Boss plenum kit also includes a shortened grid heater delete block to maintain the factory IC piping to intake manifold connection geometry . Maintaining this geometry makes the Air-Boss plenum compatible with ALL aftermarket intake manifolds and the stock mounting hardware.
GRID HEATER OPTIONS:
- A) The standard Air-Boss CR kit includes a custom height grid heater delete block.
- B) For colder climates GDP now offer the Air-Boss CR with a grid heater option. This option uses the factory grid heater and custom length stainless steel studs to accommodate the increased plenum height of the Air-Boss CR.
- C) For customers that want to swap back and forth between the heater and delete block, GDP offers both items in one package.
