Frequently Asked Questions

What coils do I need to use with this ignition system?

You must use 5 ohm coils for street operation. Using incorrect coil resistance will cause performance and starting issues.

Is this street legal everywhere?

Not legal for use in California on pollution-controlled vehicles. Check your state and local emissions laws before installing.
