Manifold spacer

Abstract

An insert adapted to be placed between a carburetor or a throttle body and an intake manifold of an internal combustion engine is provided with a fuel manifold, a nitrous oxide manifold, and one or more burst diaphragms in a wall of said insert. Said manifolds are arranged one over the other and across an opening in said insert. A plurality of orifices extend along the length of each manifold, and are arranged to direct flow outward, downward, and radially relative to the axial flow of the fuel-oxidizer mixture through the insert.
