The basic technical characteristics of sparking plugs are:
 
    -       mounting: with screw, nut or with the appropriate clamp
    -       housing: ceramics sintered Al 92-96%
    -       electrode: stainless steel
    -       ceramic housing: raw, enamelled, partly enamelled
    -       connection: direct with the connection 2.8 x 0.8 mm,
            with a high-voltage conductor with a silicone or teflon
            protection
    -       length of wires: 250 - 1200 mm
