Abstract
A skull-shaped air filter housing comprising a housing removably attached to a fitting. A jaw is hingedly attached along a lower edge of a face on the housing. The face has eye intake(s), a nose intake, and a jaw intake. When the jaw is open, air enters a housing cavity through the jaw intake. Means of rotating the jaw are disclosed, including cable actuation, spring biasing, and pneumatic actuators. The housing may contain a light for aesthetic purposes. The fitting may incorporate a fitting lumen diameter reduction at its intake to cool and compress air sent to the carburetor. When ram air enters the skull-shaped air filter housing and is sent to the carburetor, it is compressed and therefore denser, and fuel in the carburetor bowl is also compressed, resulting in a power increase in the engine.
