The Pro Mag Electronic Points Box controls the generator's energy with Field Effect Transistor (FET) technology, which is far more accurate and durable than a conventional points-triggered magneto. It keeps full-energy sparks available across the entire RPM range and holds each spark glowing for up to 26 degrees of crankshaft rotation. A built-in Soft Touch Rev Control, adjustable with plug-in modules, protects the engine from driveline failure or a missed shift, and all circuitry is Humi-Seal coated for vibration and moisture protection.

FAQ
What technology does the MSD 8106 Points Box use to control spark?
It uses Field Effect Transistor (FET) technology, which is more accurate and durable than points-triggered designs and delivers full-energy sparks across the entire RPM range.
Does the 8106 have a rev limiter?
Yes, it has a built-in Soft Touch Rev Control adjustable with plug-in RPM modules.
Is this points box legal for street use?
No. It's Emission Code 4, Racing Use Only — legal for sale and use only on unregistered competition vehicles, not on emissions-controlled street vehicles.
How long does the spark stay lit during crankshaft rotation?
The Points Box keeps each spark glowing for up to 26 degrees of crankshaft rotation.
