*Up To 36hp Increase At Flywheel *Torque Improvement Of Up To 38Ft./Lbs. At The Flywheel *Provides Even More Horsepower & Torque At Speed When Cool Air Is Forced In This vortex rammer kit replaces the restrictive stock air box assembly. This revolutionary air cleaner contains an internal vortex velocity stack. It obtains cool, pressurized air from the radiator cavity through your modified shroud. Air is forced through a sealed box, where in turn, it directly injects cold air into your intake. Lowering Manifold Air Temperature by almost 30 Degrees, cold air means more power. Results have already shown up to 36HP and 38FT/LBS at the flywheel. Running at speed has give an additional up to 10 more Hp due to the air being forced in. This is from the benefit of the pressurized air that is created at high speeds (which means there will be more h.p. at speeds over 35 MPH. 1/4 mile tests showed 3 MPH and .30 quicker E.T. This kit includes the air filter, sealed air box, and a one-piece power duct from the MAF sensor to throttle body. Instructions included. This unit is available in clear or black. Clear box will allow you to have a visual inspection of the filter assembly.
