Research Order VOR GS LOC antenna Tim's RV 10 Adventures Banks Power 99 Ford 7.3L Techni Cooler System. 3 inch mandrel bent high flow boost tubes. Eliminates restrictions for an 18% increase in flow, dramatically increasing the cooling capacity for massive continuous power, big aluminum end tanks won't burst like the plastic stock ones. Includes Twin Ram manifold inlet assembly. Banks Techni Cooler Intercooler system includes mandrel bent 3" high flow boost tubes large, high efficiency all aluminum end tanks instead of the wimpy stock plastic ones that can rupture under high boost conditions a high flow inlet that distributes air evenly across the intercooler for an 18% increase in flow and more effective cooling a wide open outlet and a thicker core area with impressive volume. Because the stock manifold inlet in early '99 Power Strokes flows more air to one side of the cylinder bank than to the other, Banks developed an innovative Twin Ram manifold inlet assembly that flows air equally to both sides of the engine for smooth, even power delivery. Note: Twin Ram is available for 1999 & 1999 1 2 (early) models only (not required for late '99 & later vehicles). Fits Trucks Built In 1998 with no catalytic converter from factory. Key Features: Wide open inlet and outlet provides 18% increase in flow. High efficiency custom machined durable cast end tanks. Cooler EGTs, more MPG & constant duty power. Improves Power, Durability & Fuel Economy. Mandrel bent 3 inch high flow boost tubes. Aluminum end tanks won't burst like stock. Thicker core area with impressive volume.
