Cap and Rotor Kits
Replacement Distributor Cap and Rotor Set
  • Fits 1985-1995 GM 4.3L V6 Distributors with an External Coil
  • Screw-On Rotor Attachment
  • Red Cap
  • Sold as a Matched Maintenance Set

    A cap and rotor are wear items in the same category as an oil filter, and carbon tracking inside a worn cap will cause a misfire that no amount of tuning will fix. This kit replaces both at once on 1985-1995 GM 4.3L V6 distributors that use an external coil.

    MSD 8430 Distributor Cap and Rotor Kit Features:

    • One distributor cap and one matching rotor.
    • Fits GM 4.3L V6 distributors with an external coil.
    • Screw-on rotor attachment.
    • Red cap.
    • MSD distributor caps and rotors are designed with performance in mind and molded from high-quality, voltage-insulating material with terminals that resist carbon tracking. Whenever the distributor cap is changed, you should install a new rotor. Likewise, if you're replacing the rotor, be sure to install a new cap as well. MSD has new kits featuring Rynite injection molded distributor caps and retainers to complete your distributor tune-up. MSD also has Cap-A-Dapts to fit large Ford-style caps onto MSD distributors.
