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.
