1. A probe for detecting electric ignition signals from a coil on plug of an internal combustion engine, the probe comprising:

  • a probe housing bearing a first conductive planar layer and a second conductive planar layer separated by and affixed to a non-conductive substrate aid adapted for placement outside of and in close proximity to a coil on plug housing, wherein said second conductive planar layer is a shielding element configured to attenuate a portion of electromagnetic radiation incident to said first conductive planar layer from a coil of said coil on plug when said second conductive planar layer is disposed between said coil on plug housing and said first conductive planar layer.
