Seems my Kitfox 4 that I just purchased came with shielded spark plug wires. The shield grounds to the ignition box behind the firewall ( box houses the coils and mags)

problem is I canít seem to find shielded wire anywhere. Did Rotax stop requiring this on the 912 ?

heres said box and the spark plug wires (blue). There is a metal retaining bracket that clamps the spark plug wires to the ignition box and affectively Grounds the wires (not showed)
