Another blip for today , amazon just dropped off some new Bosch Coils for this project .
Brazil made for German Bosch # 9 220 081 083
us # 00012 cost approx $50 each
3.0 ohms so no resistor needed
I have never ever seen a defective one !!!!
Can be mounted in any position, dont like the color paint them or use stick-um paper checkered flag etc ......
