Abstract

An apparatus and a method are provided for an air intake assembly configured for use with Pro Stock vehicles comprising fuel injection equipped engines. The air intake assembly comprises an air inlet that includes a distal opening disposed in a forward direction at a front of the vehicle and configured to direct incident air into the air intake assembly. An air duct is joined with the air inlet by way of a first coupler configured to maintain an airtight seal between the air inlet and the air duct. A throttle body adapter is joined with the air duct by way of a second coupler configured to maintain an airtight seal therebetween. The throttle body adapter is configured to establish an airtight coupling between the air intake assembly and a throttle body of the engine, such that the incident air is directed into the throttle body.

Dependent claims

An air intake assembly configured for use with a vehicle comprising an engine equipped with a throttle body electronic fuel injection (EFI), the air intake assembly comprising:

an air inlet configured to be disposed at a front of the vehicle, the air inlet having a first distal end of a first shape and a first proximal end of a second shape, the air inlet having a first cross-section that tapers between the first shape of the first distal end of the air inlet to the second shape of the first proximal end of the air inlet, and wherein the taper of the air inlet is comprised of a reverse curve-shape that extends proximally from the first distal end of the air inlet toward the first proximal end of the air inlet, the reverse curve comprising an upwardly concave portion that is followed by an upwardly convex portion;
an air duct to receive incident air from the air inlet, the air duct having a second distal end and a second proximal end, the air duct having a second cross-section that tapers from the second distal end to the second proximal end;
and
a throttle body adapter coupled to the second proximal end of the air duct.

maintaining an airtight seal between the air inlet and an air duct by way of a first coupler, wherein the air duct includes a second distal end and a second proximal end, the air duct having a second cross-section that tapers from the second distal end to the second proximal end;
joining the air duct with a throttle body adapter by way of a second coupler;
and
directing the incident air through the throttle body adapter via the second coupler.
