Abstract
A sealed intake air system incorporates a positive connection seal interface between the air filter and the airbox with captive fasteners to provide a positive connection between the air filter and the one-piece airbox.
Claims5
An intake air system comprising:
- a one-piece sealed housing airbox with an intake opening and an air filter interface;
- a rigid air filter base with a filter flange configured to engage the air filter interface in the airbox;
- a plurality of captive fasteners secured to the rigid air filter base for securing the filter flange to the airbox;
- an air filter with filter media secured between the rigid air filter base and a top;
- a bellows coupler operably connected to the rigid air filter base;
- and
- an intake tube operably connected to the bellows coupler to conduct filtered air to an engine air intake;
- wherein the rigid air filter base and the top each have a three-angle throat surface angled with three different angles to conform to the filter media.
