Dawsonville GA: Air cleaners are not normally noted for their ingenuity. But this one might be.
The hallmark of a great air filter is one that does more. Measuring 14 inches in diameter and supplied with a 3in deep filter element and featuring a recessed base to maintain a low profile, Demon Carburetion’s newly designed air cleaner (PN 786004) was conceived initially to suit the latest 625cfm Street Demon. But senior Demon designer, Larry Tipton, cleverly introduced a return flange to the bottom of its recessed base, at the gasket surface, enabling it to accommodate not only the Street Demon but also all modular-style Demon carburetors, including those with choke-operating mechanisms.
Return flange provides adequate margin of operating clearance.
Early Demon carburetors were principally designed for racing engines and as such had no choke towers. Later models prepared for the hot rod market, however, exhibited streamlined choke towers with linkages that sometimes interfered with existing air cleaners. On this new Demon air cleaner the return flange provides an adequate margin of operating clearance.
Replacement air filter elements, 3 or 4in deep, are readily available from most auto parts stores.
