This single fire coil was developed for the use e.g. in
GDI (turbocharged) high performance engines. It is
designed for direct cylinder head mounting.
For this single fire coil the customer can define thelength of the spark plug connector.
The main benefits of this high performance coil are
its high energy capability and a very good provided
high voltage.

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.
This coil is only for use with engine control units having an integrated ignition power stage, e.g. IGBT IRG4BC40S or BIP.
For technical reasons the values of the coils may vary.
Please regard the specified limit values (see “Electrical Data”).
Usage above Iprim = 16 A or 40 kV may reduce the lifetime.
Please find further application hints in the offer drawing at ourhomepage.
Dwell time

In case of ignition-caused malfunctions, please use screened
sensor wires.
