The COP adapter series uses new sensor technology and is designed to be easily indexed for accurate cylinder-to-cylinder comparison.  The COP adapter also provides an engine RPM signal to the kV Module.

The Snap-on COP (coil-on-plug) 7 AdaptER is a non-intrusive capacitive pickup that fits directly into the existing slot on the coil assembly of some Mercedes-Benz coils.
