Bosch Electronic Coil

[Tham]

I found this Bosch coil at the salvage yard where

I had bought the Nippondenso electronic

distributor earlier for my Corolla's 4K.

It's marked "For Transistor Ignition" and

must have been salvaged from a BMW. It has

part No. 0 221 118 335 carved at the bottom.

 

Is this the famous Bosch "black" electronic coil,

and could it be used with the 4K's Nippondenso

electronic distributor ?

 

I measured it, and the coil's primary winding has

a very low resistance of just about 0.6 ohms, versus

1.5 ohms or more for typical Japanese electronic coils.

 

Secondary resistance is equally low, at 6.3 kohms,

versus typically 10 to 12 kohms for Japanese coils.

 

Wonder if it might burn out my igniter. The salvage

yard owner said it was meant to be used on German

engines' electronic systems.
