My car has two double coils driven by the ECU (e.g. Renault/Citroën). Which MSD kit fits?

If each double coil receives two wires from the ECU, you can use our Saxo VTS-type kit or the MSD Blaster SS 8207 with the MSD 5520, giving at least 20% better spark than a new stock coil. Measure the resistance and length of one of your wires first so we can confirm they are suitable for use with an MSD ignition box.
