Abstract: An air delivery device for use in delivering air from the outlet of a turbocharger to a carburetor. The device has an intake passage extending from an inlet through an appended portion extending to an outlet. A flow divider extends diametrically through the passage from the inlet to the outlet. The flow divider provides passage into an upper channel and a lower channel. The upper channel delivers air to the front barrels of a four-barrel carburetor and the upper channel delivers air to the rear barrels of a four-barrel carburetor. The intake passage has a frustoconical shape which increases in diameter from the inlet to the bend portion.
