Patent ID: 7347883

Claim:
An aftermarket motor vehicle air filtration system including a battery tray for installation within a stock OEM engine compartment comprising: a) a filter housing having a plurality of contiguous walls extending upwardly from a floor to an upper edge with one of the walls defining an air outlet port; b) a battery tray formed integrally with the housing and extending along a longitudinal axis generally parallel to one of said walls so that a battery placed on the tray is positioned within the housing; c) an air intake tube secured to the housing and having an upstream end projecting through the air outlet port and a downstream end through which filtered air passes on route to an air intake of an internal combustion engine; d) a filter element having a base and top portion with the base portion connected to the upstream end of the air intake tube and a top portion; and e) the filter element extending upstream from the base portion alongside a battery positioned on the tray and above the floor to the top portion, the filter element sharing the common air space within the housing with the battery to allow for an increase in the volumetric filter flow rate over the flow rate achievable in the stock system.
