HEI Tune-Up Kit - w/Blue Cap

The Pertronix Ignition HEI Tune-Up Kit with Blue Cap is a complete distributor overhaul solution designed for classic Chevrolet, Buick, Oldsmobile, and Pontiac V8 engines. This comprehensive kit addresses the core components that wear over time, delivering restored ignition reliability without requiring a full engine rebuild. Whether you're restoring a vintage muscle car or maintaining a classic cruiser, this tune-up kit provides the essential components needed to ensure consistent spark delivery and predictable engine performance.

The kit includes a complete set of OEM-quality distributor internals: a blue distributor cap, ignition coil, ignition module, rotor, vacuum advance mechanism, and vacuum canister. The vacuum advance system is critical for optimal timing control across varying engine loads—it automatically adjusts spark timing to enhance fuel efficiency at cruise and maximize power under acceleration. Each component is engineered to work as an integrated system, eliminating compatibility guesswork and reducing installation time. The robust construction ensures durability through extended driving seasons without premature wear or voltage leakage.

This tune-up kit is ideal for owners of first-generation HEI distributor equipped V8s from General Motors' classic lineup. Installation requires basic mechanical skill and standard ignition tools; the modular design allows replacement of individual components if needed for future maintenance. Proper installation restores cold-start reliability, eliminates spark scatter that causes rough idling, and reduces fuel consumption typical of worn distributor caps and corroded rotors. For collectors and enthusiasts seeking plug-and-play ignition system refresh without electronic conversion, the Pertronix HEI Tune-Up Kit delivers straightforward, proven performance.
