You may have an old Bosch Blue Coil and while that might seem good enough, more than likely it is pretty tired and dried out. Coils do get old and they do provide less and less power. If your coil is over 10 years old please replace your coil at the same time as doing the distributor.
Installation instructions:
Red Wire: + on coil
Black Wire: – on coil
Fits:
Alfa with 4 cylinder
1300cc-2000cc
*NOTE: 1982-88 L-Jet cars need extra mods to remove/bypass the factory spark ECU.*
*NOTE: DO NOT USE ON SPIDERS WITH MOTRONIC IGNITION (1990-94)*
*NOTE: No warranty without purchase of a NEW Coil (see above additions)*
*NOTE at this time all Bosch Blue coils are on back order and we do NOT know when they will be available. But we have a great option listed above.*
