PLEASE INQUIRE FOR YOUR SPECIFIC APPLICATION...
NOTE; BOSCH CLASSIC IGNITION COILS are currently out of production.
Technical Note:
On models equipped with transistor module the arcing is drastically reduces since
less than a ampere flows through the points , however the resistor should be installed to
protect the coil and improve its longevity , the blue coil originally installed on those
models has a distinct construction, the thickness and ratio of the coil windings are designed for
a discharge of the transistor module ,
