GM Distributor Caps
    Distributor Cap
  • GM V8 HEI
  • Extreme Output
  • Stainless Steel Terminals

    With the introduction of our 20 Amp Extreme HEI Module, MSD needed an HEI Cap that could withstand the high output. The answer was to mold their own HEI Cap. The cap is supplied with a stock GM rotor bushing and MSD's Low Resistance Bushing (121-8412) to cover whatever ignition type you are running. Also included is the Coil Cover (121-84022) which has the wire retainers built in.

    Applications:
  • GM V8 HEI Distributors
  • MSD Dristributor 121-8365
  • MSD Distributor 121-8362
