ABSTRACT:
A method of making an ignition device and center wire assembly that includes first, second and third electrode members, a conductive seal, and a noise suppressing seal. The method locates the first electrode member at an axial end of the center wire assembly near a spark gap and the third electrode member at an axial end of the center wire assembly such that it receives an electrical ignition pulse and a second electrode member between the first and third electrode members. Furthermore, the method locates the conductive seal between the first and second electrode members and the noise suppressing seal between the second and third electrode members.
