MSD wires for my Honda Integra don't fit my distributor cap. Why?

MSD wire sets 32349 and 32343 are both for the Integra; the only difference is colour (black is no longer produced, only red). These wires are made for the MSD distributor cap, not the stock cap. Send us a photo of your cap. If needed we can supply the correct boots and terminals (e.g. MSD 3321) to adapt the wires.
