An extender for connecting a high-voltage source to a spark plug has a conductive member, a tube having an interior passageway in which the conductive member is positioned therein, and a boot affixed over an exterior of the tube. The boot is formed of a material having a rigidity less than a rigidity of a material of the tube. The boot has a first end adapted to connect with the high-voltage source and a second end adapted to be connected to the spark plug such that the conductive member is in electrical connection with the spark plug and the high-voltage source. The conductive member includes a spring that is adapted to electrically connect with the high-voltage source and the spark plug.
