I just bought a 1993 XJS Jaguar convertible with 93,000 miles on it and I need to do some maintenance on it. So, I have replace the plugs, cap, rotor, plug wires and now I'm looking for a new ignition coil. From what I have seen available locally for this car, it seems the primary resistance is anywhere from 0.6 to 1.5. ohms. My service manual says 0.9 to 1.1 ohms. primary resistance. I need to make sure I get the right one for my car. Are the values of the local coils too far out of range?

 

generally that spec is what it needs to be within to operate, since the other coils are inside the OEM spec you should be fine.

 

Sidescrollin, Thanks for your feedback. I think I will go with the Bosch brand.
