Measured values are without loom resistance. Loom resistancemust be less than the primary resistance. The needed dwell timeis to be verified through current measurement

Installation Notes
During mounting of the spark plug please pay attention that fullclamping and proper contacts are made to ensure safe connection between coil and spark plug.
The coil PS-T has an integrated transistor and requires an ECU
with internal ignition drivers, e.g. MS 4.x or MS 4.x Sport.
For technical reasons the values of the coils may vary.
Please regard the specified limit values.
Please find further application hints in the offer drawing at ourhomepage.
In case of ignition-caused malfunctions, please use screened
sensor wires.
