MSD Low Resistance HEI Distributor Bushing 1-3 Ohms Solid Bronze Tip 8412

Description

If you’re running a high-output ignition system on your GM HEI distributor, excessive resistance in your cap-to-rotor connection will cost you voltage, heat your components, and shorten their lifespan. The MSD 8412 Low Resistance HEI Distributor Bushing replaces the factory design with a solid bronze tip that drops resistance to just 1–3 ohms, ensuring efficient secondary voltage transfer and keeping your distributor cap and rotor running cooler under sustained high-RPM conditions. Whether you’re building a street machine or tuning a race engine, this is a straightforward upgrade that pays dividends in reliability and longevity.
