Frequently Asked Questions

Will this fit my EFI Harley?

No — this coil is for carbureted models only. EFI-equipped bikes require a different Compufire coil designed for electronic fuel injection.

Can I use this with a points ignition?

No — this coil is not compatible with points or Dyna S ignition systems. Verify your current ignition type before ordering.

Is this a direct bolt-on replacement?

Yes, if your bike currently uses a single-fire ignition. Mount it using the existing bracket and reconnect the primary and secondary wires.

What year Sportster does this fit?

Fits 1972-2001 Sportster (XL) models with single-fire ignitions. Check your specific year's ignition configuration before purchase.
