Description
Worn or damaged distributor boots compromise ignition timing and increase misfire risk—especially critical in high-RPM applications where spark plug wire connections demand reliability. The MSD 8849 HEI kit eliminates connection failures with high-temperature silicone construction and secure crimp terminals, keeping your ignition system firing consistently across the entire RPM band. Whether you’re running a stock engine or a modified build, quality boots and terminals are non-negotiable for stable performance and tuning.
