Abstract: A modular air intake system is presented. The system comprises a variety of modular components that may be coupled together to form a desired air intake system configuration for an automobile engine. Each modular component has a plastic structure with chrome plating, resulting in improved insulation and heat reflection characteristics for better engine performance. An intake system may be configured to fit into virtually any automobile engine compartment, because the components may be coupled in any combination, and the angular connection relationship between any two components is adjustable. A locking split-collar may be used to lock the junctions between modular components to provide a fixed configuration.

Abstract: An oil filler cap with an integrated oil directing funnel. The cap is configurable to fit many automobile makes and models, and is configured to accept the threaded top end of standard quart containers. The integrated funnel is extendible to a fully open position wherein it facilitates replacement of engine oil in a manner preventing spillage onto the engine block and vicinity. Once the outlet of a standard quart container of engine oil is placed into the collapsible funnel to engage the cap structure, the funnel may then collapse to its resting position while passing engine oil from the standard quart container to the engine block. Drainage holes in the cap recapture oil that seeps through or clings to the integrated funnel.

Abstract: A protective and decorative cover for application to bolts, nuts and the like. The cover comprises a retainer made of a resilient compressible material having legs which align with the flats of a bolt head or nut. A generally cylindrical cap is then applied over the retainer. The internal diameter of the cap provides an interference fit with the legs of the retainer thereby compressing them against the flats of the bolt or nut. The exposed head of the bolt or the nuts is thus fully enclosed by the cap and protected from the elements. The cap may have a decorative shape and finish that is particularly desirable in automotive, motorcycle and marine applications.
