What's in the Box

The cap and rotor of any ignition system must be considered mainte­nance items. Just as you change the oil and filter of your car, you should always replace the cap and rotor as a set. To make things easy, we now offer these Cap and Rotor Replacement Kits.

MSD 8225 HEI High Performance Direct Replacement Coil
(Part #5478225)
                        

HEI owners now have a choice to replace their stock coil with the MSD High Energy Unitized Coil for GM HEI Distributors. This coil is a direct re­placement of the stock coil. The coil features special low induc­tance, high temperature windings which charge faster to give you increased spark energy at higher rpm. The premium epoxy filled construction is designed to withstand harsh race applications as well as the wear and tear that daily usage dishes out, and still deliver more spark energy to the spark plugs.

  • Direct performance replacement for GM HEI coil-in-cap distributors
  • 70:1 turns ratio and lower primary resistance produce high voltage output
  • Full power sparks to 9,000 RPM when used with 8364 MSD HEI Module
  • Recommended for use with MSD HEI Module PN 8364

MSD 31359 8.5mm Spark Plug Wires Set, Chevy HEI, Over Valve Cover
(Part #54731359)
                        

The MSD 8.5mm Super Conductor Wire is "the" performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire; incredibly low resistance without electronic interference! In a single 12 inch length of low resistance spark plug wire there is only 40 - 50 ohms of resistance! That is the lowest resistance of any helically wound wire.

To accomplish this, MSD uses a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight in fact, that there is over 40 feet of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference (EMI) "choke". This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. The outer sleeve that surrounds the conductor assembly is just as impressive. A proprietary blend of silicone and synthetic material produce a sleeve that is highly resistant to high heat as well as abrasion and tears.

Performance Distributors 111111 Battery and Tachometer Connector
(Part #91013201)
                        

These plastic insulators and brass terminals make your power supply connection and tach connection to the DUI Distributor super easy! They plug directly into the cap and coil assembly and the locking tabs prevent lost connections due to vibration. The Battery and Tachometer Connectors are priced separately so one of each will be needed for the hot wire and tach hookup.

Accel 170072 HEI Wiring Pigtail
(Part #105170072)
                        

Finally, a dual HEI connector for GM HEI “Coil In-Cap”. The Dual HEI Connector helps clean up your engine bay by eliminating the use of single spade connectors to make battery and tachometer connections. Also holds the 12 volt and tachometer wires securely in place. Made from hi-temperature durable plastic to withstand all extreme conditions of an engine bay. The easily seen, 10” long, red and green wires identify battery and tachometer.

  • Wire your HEI distributor like the factory
  • Red and green wires identify battery and tach leads
