Bosch Motorsport | Ignition Coil C90i-WG

Ignition Coil C90i-WG

 Max. 35 kV
 Min. 90 mJ
 Connection for high voltage wire
 Max. 15,000 1/min
 Developed for Turbo-GDI engines

This single fire coil was developed for the use e.g. in
GDI (turbocharged) high performance engines. It is
designed to connect a high voltage wire on the coil.
The main benefit of this high performance coil is its
high energy capability.

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 (high voltage wire).
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 35 kV may reduce the lifetime.
Please find further application hints in the offer drawing at ourhomepage.
Design NoteWe strongly recommend the design of the spark plug shaft has toensure that there are no sharp edges in the shaft geometry due todesign or machining. Only in compliance with this recommendation, a proper function can be ensured.
