Description
At high RPM, your ignition system only has microseconds to deliver maximum voltage to each cylinder—and a worn or inferior rotor will cost you that critical spark. The MSD Extreme Output Rotor 84101 replaces the weak link in your HEI distributor with a low-resistance brass terminal that resists carbon tracking and maintains peak voltage transfer, even under sustained boost or nitrous conditions. If you’re serious about reliability and performance, a quality rotor isn’t optional—it’s foundational.
