Abstract

An apparatus and a method are provided for an aircharger air intake system for filtering and conducting an airstream to an air intake of an engine. The aircharger air intake system includes an air filter comprising a filter medium configured to entrap particulates flowing within the airstream. An air box comprising one or more sidewalls and a mount wall is configured to support the air filter within an engine bay. The air box is configured to be mounted, or fastened, onto the engine. An intake tube is coupled with the air filter and configured to conduct the airstream to the air intake of the engine. The intake tube is configured to be coupled with an air temperature sensor or a mass air sensor of the engine. An adapter is configured to couple the intake tube with the air intake.

First claim

What is claimed is:

1. An aircharger air intake system for filtering and conducting an airstream to an air intake of an engine, comprising:
an air filter configured to entrap particulates flowing within the airstream, wherein the air filter is configured to be retained between an air scoop and an air scoop base and wherein the air filter comprises a pliable strip configured to be pressed against an interior surface of the air scoop upon fastening of the air scoop onto the air scoop base, such that the airstream entering the air scoop passes through the air filter before entering into the air intake of the engine;
an intake tube coupled with the air filter and configured to conduct the airstream to the air intake; and
a breather plate configured to couple the intake tube and the air intake.

2. The air intake system of claim 1 , wherein the breather plate is comprised of a velocity stack portion that is configured to direct the airstream from the intake tube into the air intake of the engine.

3. The air intake system of claim 1 , wherein the breather plate further comprises one or more mount portions configured to receive bolts so as to facilitate fastening the breather plate to the engine.

4. The air intake system of claim 3 , wherein O-Rings are disposed above and below the mount portions to provide cushioning between the breather plate, the bolts, and the engine.

5. The air intake system of claim 1 , wherein the breather plate is coupled to the air intake by way of a plurality of suitable fasteners extending through countersunk holes disposed in the breather plate and engaged with threaded holes in the air intake, a gasket being disposed between the breather plate and the air intake and configured to establish an airtight seal there between.

6. The air intake system of claim 1 , wherein the intake tube is coupled to the breather plate by way of a plurality of threaded studs that are engaged within threaded holes in the breather plate, such that remaining portions of the threaded studs extend from the breather plate, each of the remaining portions extending through a hole disposed in the intake tube and receiving an acorn nut that is tightened to fasten the intake tube to the breather plate, a gasket being disposed between the intake tube and the breather plate and configured to establish an airtight seal therebetween.

7. An aircharger air intake system for filtering and conducting an airstream to an air intake of an engine, comprising:
an air filter retained between an air scoop and an air scoop base and configured to entrap particulates flowing within the airstream, wherein the air filter comprises a pliable strip configured to be pressed against an interior surface of the air scoop upon fastening of the air scoop onto the air scoop base, such that the airstream entering the air scoop passes through the air filter before entering into the air intake of the engine;
a velocity stack portion comprising the air scoop base; and
a breather plate configured to couple the air scoop base and the air intake.

8. The air intake system of claim 7 , wherein the air scoop is fastened to the air scoop base by way of a plurality of fasteners inserted through holes in the air scoop and fixedly engaged with threaded holes in the air scoop base.

9. The air intake system of claim 7 , wherein the air scoop includes a forward opening and one or more rearward openings, the forward opening being configured to capture an oncoming airstream due to vehicle motion, and the one or more rearward openings being configured to allow air to enter the air scoop in absence of the oncoming airstream, a mesh insert being fastened inside the air scoop and covering the one or more rearward openings to increase aesthetic appeal of the air scoop.

10. The air intake system of claim 7 , wherein the velocity stack portion is configured to direct the airstream from an interior of the air filter through an air opening of the breather plate and into the air intake of the engine.

11. The air intake system of claim 7 , wherein the breather plate further comprises one or more mount portions configured to receive bolts so as to facilitate fastening the breather plate to the engine, and wherein O-Rings are disposed above and below the mount portions to provide cushioning between the breather plate, the bolts, and the engine.

12. The air intake system of claim 7 , wherein a plurality of fasteners are inserted through holes in the air scoop base and fixedly engaged within threaded holes disposed in the breather plate so as to fasten the air scoop base to the breather plate, a gasket being disposed between the air scoop base and the breather plate establishing an airtight seal there between.

13. The air intake system of claim 7 , wherein the breather plate is coupled to the air intake by way of a plurality of suitable fasteners extending through countersunk holes disposed in the breather plate and engaged with threaded holes in the air intake of the engine, a gasket being disposed between the breather plate and the air intake establishing an airtight seal there between.

14. An aircharger air intake system for filtering and conducting an airstream to an air intake of an engine, comprising:
an air filter configured to entrap particulates flowing within the airstream, wherein the air filter comprises a pliable strip configured to be pressed against an interior surface of an air scoop upon fastening of the air scoop onto an air scoop base, such that the airstream entering the air scoop passes through the air filter before entering into the air intake of the engine;
a filter back plate configured to couple the air filter and the air intake;
a velocity stack configured to be disposed on the filter back plate; and
a filter lid configured to be fastened onto a cap of the air filter.

15. The air intake system of claim 14 , wherein the filter back plate and the filter lid are comprised of a rigid material capable of withstanding the temperature and air pressure associated with operation of the engine.

16. The air intake system of claim 14 , wherein the filter back plate comprises an air opening that receives the velocity stack, such that an airtight seal is established between the filter back plate and the air intake of the engine, the velocity stack being configured to direct the airstream from an interior of the air filter into the air intake.

17. The air intake system of claim 14 , wherein a plurality of fasteners are inserted through the velocity stack, through intake mount holes disposed in the filter back plate, and engaged with threaded holes of the air intake of the engine, such that tightening the plurality of fasteners fixates the filter back plate to the intake of engine and causes the velocity stack to establish an airtight seal between the filter back plate and the air intake.

18. The air intake system of claim 14 , wherein the filter back plate further comprises one or more mount portions configured to receive bolts so as to facilitate fastening the filter back plate to the engine, and wherein O-Rings are disposed above and below the mount portions to prevent unfiltered air from bypassing the air filter and to provide cushioning between the filter back plate, the bolts, and the engine.

19. The air intake system of claim 14 , wherein a plurality of threaded standoffs are disposed between an interior of the air filter and the filter back plate, a plurality of fasteners being inserted through holes in the cap and fixedly engaged with the threaded standoffs, and a plurality of fasteners being inse
