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.
