Distributor Caps - V6 & V8 Presto

Sierra Distributor Caps are injection-molded, glass-filled polyester with a high-luster finish for a complete, high-quality cap.

No tune-up is complete without replacing the distributor cap, since the old one may have developed microscopic cracks that become electrical pathways at high voltages.
Sierra uses a special composition material that retains high dielectric strength under elevated temperatures, and brass inserts to eliminate the formation of aluminum oxide.
Caps are molded with perfect roundness assuring a better fit.

• Brass inserts eliminate formation of aluminum oxide
• Injection-molded, glass-filled polyester for high dielectric strength
• Close tolerances assure a perfect fit
