Abstract
A replaceable air filter for filtering inlet air to an engine has a heavy-duty housing which protects the filter element from heat and damage due to improper handling. The durable housing further provides additional surfaces for mounting the air filter to a combustion engine. The filter element inside the housing is permanently sealed to the housing, thereby reducing the risk of unfiltered air from bypassing the filter element to enter the air intake tube. Because the filter element is permanently attached to the housing, the entire air filter must be replaced during routine maintenance, thereby reducing the risk of loose dirt from spent filters being drawn into the engine. A snout member is injection molded to have an air outlet which may be sized for connection with either a flexible or rigid air intake tube.
