the combustion process. But when you start adding performance mods, one spark might not be enough to get the job done.
Ignition boxes boost the combustion process by sending multiple sparks to the plug. Multiple-spark ignition ensures the
fuel mixture will reach complete combustion at a wider range of RPMs. This boosts your Bronco’s starting efficiency and

limits. Some are digital and have a built-in LED for system checks. The black or red finishes will add a nice touch
