Abstract

An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.

Dependent claims

A flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine, comprising:

a base comprised of a seal that is configured to contact the flat surface and connect an interior of the flangeless air filter with an air intake duct of the internal combustion engine;
a cap configured to direct an intake airstream into the flangeless air filter;
and
a filter medium disposed between the base and the cap, the filter medium being configured to remove contaminants and particulate matter from the intake airstream entering the air intake duct, wherein the seal is comprised of a pliable material amendable to being compressed so as to establish an airtight connection between the base and the flat surface, wherein an externally facing surface of the seal is a flat, ridgeless surface configured to establish the airtight connection and wherein the flat, ridgeless surface spans from an interior opening of the base to an exterior edge of the base, wherein a mounting bracket is coupled with the base and includes a plurality of protrusions configured to enable coupling with the flat surface, wherein the protrusions extend outward relative to the interior opening of the base, the mounting bracket being a generally ring-shaped member comprised of an opening that receives a portion of the filter medium adjacent to the base.
