1998 Mercury Sable Cold Air Intake (CAI) Prototype Sketch - Tube & Filter Layout

This document is a simple black-and-white line drawing (schematic sketch) uploaded as "CAI Prototype.JPG" to a 1998 Mercury Sable gallery. It depicts a prototype cold air intake (CAI) design: a tube that begins at an upper-left inlet opening, angles downward through multiple bends and segmented sections (which appear to represent couplers, joints, or tube segments), and terminates at a cone-shaped air filter element at the lower left of the drawing. The sketch contains no text whatsoever — no dimensions, measurements, part numbers, material callouts, or labels. As such, a reader can only learn the general routing shape and conceptual layout of the proposed intake: an inlet at the top, a long descending run with roughly four to five joint or coupler locations, a lower horizontal run, and a conical filter at the end. Without dimensions or annotations, the drawing serves purely as a visual concept/prototype illustration rather than a build specification. Its applicability to the 1998 Mercury Sable cannot be confirmed or contradicted from the drawing itself, since no vehicle, engine, or year information appears in the image.
