GDP Air-Boss VP Intake Plenum & Grid Heater Delete Kit 98.5-02 CumminsEGT's running too high? Can't use all of the fuel you have available? The Air Boss VP plenum gives the largest bolt on flow increase possible short of milling the cast plenum off the head and installing a fabricated intake plenum. The Air Boss VP isn't just a replacement flat aluminum plate as seen in other designs. The Air Boss VP 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 Air-Boss VP plenum gives the largest bolt-on flow increase possible short of milling the cast plenum off the head and installing a fabricated intake plenum. The Air-Boss VP isn't just a replacement flat aluminum plate as seen in other designs. The Air-Boss VP 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 our plate design we open up the plenum area to the starving rear cylinder by a full 20%. By increasing airflow to the rear cylinders we reduce EGT's and allow you to run even higher fueling levels.The Air-Boss VP 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 VP compatible with ALL aftermarket intake manifolds and the stock mounting hardware.
GRID HEATER OPTIONS:
- The standard Air-Boss VP kit includes a custom height grid heater delete block.
- For colder climates we now offer the Air-Boss VP with a grid heater option. This option uses the factory grid heater (no delete included) and custom length stainless steel studs to accommodate the increased plenum height of the Air-Boss VP.
- For customers that want to swap back and forth between the heater and delete block we offer both item in one package.

Lovely Bag
Absolutely love this bag. The strap is a little tricky to adjust but once you do it’s are perfect. The whole thing came in a duster bag with material to protect the interior and integrity of the shape. Great product.
