Does anyone know the supplied voltage to our coils. Is it 12 volts?
I am nearly 99% sure that it's 12 volts... it definitely isn't 5v. I remember seeing 12 volts at the connector.
Just installed new ones in mine. OEM Bosch from Amazon. Like $65 ea. Same part # stamped on both. Only difference I can see is the factory original parts says made in Germany and the new ones say made in Slovenia. You can buy the stickers that diagram the corresponding cylinders from Ricambi for $0.01
