Claim 4

The air intake filter according to claim 2 wherein the means for intaking air comprises a rectangular port.

Claim 5

The air intake filter according to claim 3 further comprising means, disposed in said removable lower portion, for separating water from air entering the rectangular port.

Claim 6

The air intake filter according to claim 9 wherein the means for separating water comprises an internal surface of said removable lower portion and an upstanding wall, abutting the internal surface, having at least one aperture therethrough.

Claim 7

The air intake filter according to claim 5 wherein said internal surface is planar.

Claim 8

The air intake filter according to claim 6 wherein said internal surface forms one side of the rectangular port.

Claim 9

The air intake filter according to claim 7 wherein the upstanding wall joins the internal surface at an angle of about 90°.

Claim 10

The air intake filter according to claim 8 wherein said means for communicating air includes tubular means, connecting the housing upper portion and an air intake of said automobile engine for supplying filtered air to said automobile engine from said housing.

Claim 11

An air intake filter for an internal combustion engine disposed in an automobile engine compartment beneath a hood and behind a radiator, said air intake filter comprising: a housing sized for mounting beneath the hood with an air intake thereof positioned in front of said radiator when the housing is mounted beneath the hood; tubular means, connecting said housing and an air intake of said automobile engine, for supplying filtered air to said automobile engine from said housing; filter means, disposed in said housing, for removing solid particulates from air entering the housing air intake; and means, separate from said filter means, for separating water from air entering the housing air intake before the entering air enters the filter means comprising an internal housing surface disposed at an acute angle with the housing air intake and at least one aperture disposed in a rear housing wall subtending the internal housing surface.

Claim 12

An air intake filter for an internal combustion engine disposed in an automobile engine compartment beneath a hood and behind a radiator, said air intake filter comprising: a housing sized for mounting beneath the hood with an air intake thereof positioned in front of said radiator when the housing is mounted beneath the hood; tubular means, connecting said housing and an air intake of said automobile engine, for supplying filtered air to said automobile engine from said housing; filter means, disposed in said housing, for removing solid particulates from air entering the housing air intake; and means, separate from said filter means, for separating water from air entering the housing air intake before the entering air enters the filter means comprising an internal housing surface disposed at an acute angle with the housing air intake and at least one aperture disposed in a rear housing wall subtending the internal housing surface.

Claim 13

The air intake filter according to claim 10 wherein the internal housing surface is planar.

Claim 14

The air intake filter according to claim 11 wherein the rear wall joins the internal surface at an angle of about 90°.

Claim 15

An air intake filter for an internal combustion engine disposed in an automobile engine compartment beneath a hood, said air intake-filter comprising: a housing sized for mounting beneath the hood, said housing comprising an upper portion and a removable lower portion, said lower portion including an air intake; filter means, disposed between said upper and lower housing portions, for removing solid particulates from air entering the air intake; tubular means, connecting the housing upper portion and an air intake of said automobile engine, for supplying filtered air to said automobile engine from the housing upper portion; and means, disposed in said removable lower portion, for separating water from air entering the lower portion air intake before the entering air enters the filter means.

Claim 16

An air intake filter for an internal combustion engine disposed in an automobile engine compartment beneath a hood, said air intake-filter comprising: a housing sized for mounting beneath the hood, said housing comprising an upper portion and a removable lower portion, said lower portion including an air intake; filter means, disposed between said upper and lower housing portions, for removing solid particulates from air entering the air intake; tubular means, connecting the housing upper portion and an air intake of said automobile engine, for supplying filtered air to said automobile engine from the housing upper portion; and means, disposed in said removable lower portion, for separating water from air entering the lower portion air intake before the entering air enters the filter means.

Claim 17

The air intake filter according to claim 13 wherein the means for separating water comprises an internal surface of said removable lower portion and an upstanding wall, abutting the internal surface, having at least one aperture therethrough.

Claim 18

The air intake filter according to claim 14 wherein the upstanding wall joins the internal surface at an angle of about 90°.

Claim 19

The air intake filter according to claim 15 wherein the internal surface is planar.
