The Best Way to Trigger Your Ignition
Stable ignition timing is necessary for high-horsepower engines with extreme cylinder pressures. MSD uses a non-magnetic pickup triggered by powerful magnets embedded in the trigger wheel. The sensor brackets feature a long adjustment slot providing a range of accurate timing adjustments.
