Pro Flow + Cold Air Induction System for the C5 Corvette 
                                                                                    by the Vette Doctors Inc.

The restrictive C5 LS-1 and LS6 Factory Stock Air Box is replaced with a specially designed cold air induction system called Pro Flow+. It allows fresh air to enter through a modified hole in the shroud and pass through a Hi Flow K&N Filter. The increased air flow provides a gain of 19.9 Torque and 19.3 HP at 5100 RPM and 17.4 Torque and 19.3 HP at 5800 RPM at the rear wheels, on the Dyno. At the rear wheels and standing still!. At higher RPM's the air being drawn in to the Pro Flow+ system is contained and pressurized creating a ram effect that in turn makes additional horsepower that doesn't show up on the dyno. Throttle Response is also greatly improved, no more bog at low rpm.
