Abstract
An ignition coil assembly with extension for electrical connection of an ignition plug of an endothermic engine, wherein the extension (10) comprises an essentially tubular hollow body (11) having a first end area (10.1) engaged, in a detachable manner, on the free end of an ignition plug, and electrical connections (10.26, 20, 10.36), provided for the transmission of high voltage electrical energy between an electrical/electronic member of the ignition coil and the ignition plug. The electrical connections (10.26, 20, 10.36) comprise at least one filter (20) of the high frequency electromagnetic disturbances produced by the operation of the coil, wherein a winding of electrically conductive wire surrounds a central core (20.3) in ferromagnetic material dispersed in a polymer base.
