Our inlet ducts were designed using computer-aided analysis and wind tunnel testing for maximum air flow with minimal drag. They are molded from tough, high-impact black HDPE plastic. An integral flange (approximately 3/4" wide) makes them easy to rivet to body panels or bond to composite panels with epoxy.
This Small size has dual outlet nipples that accept our 3" duct hose (sold separately). Approximately 9.5" long x 5" wide rectangular opening is ideal for mounting in the center of a bumper cover or air dam. Some builders have even adapted this size to fit in a rectangular headlight opening.
Note: These ducts are designed and built for racing use. They are not built for show cars. You can sand and paint them, but do not expect a "show-quality" finish out of the box.
