About Our HEI Kits

HEI (High Energy Ignition) distributor kits provide a complete ignition solution by combining key components into a single, easy-to-install system. These kits are designed to deliver strong, consistent spark output while simplifying wiring and improving overall engine reliability.

Upgrading to an HEI kit can improve ignition performance, resulting in better throttle response, smoother idle, and more consistent combustion. These systems are especially popular for classic vehicles and performance builds where reliability and ease of installation are important.

HEI distributor kits typically include a distributor, ignition module, and may also be paired with spark plug wires or other supporting components. By combining these parts into a complete package, HEI kits help ensure compatibility and simplify the upgrade process.

These kits are commonly used on Chevy Small Block and Big Block engines, as well as other compatible applications. Their self-contained design makes them a popular choice for replacing older ignition systems or upgrading from points-style distributors.

Whether you're restoring a classic engine or building a performance setup, HEI distributor kits provide a reliable and efficient ignition solution with improved spark delivery and simplified installation.

HEI Kits FAQs

What are the benefits of an HEI ignition system?

HEI systems offer improved spark strength, better reliability, and simpler wiring compared to older ignition systems. They can improve throttle response, idle quality, and overall engine performance.

Do HEI distributor kits increase horsepower?

HEI kits can improve combustion efficiency by delivering a stronger and more consistent spark. While they may not add large horsepower gains on their own, they support better engine performance and reliability.

Are HEI kits easy to install?

Yes, HEI distributor kits are known for their simple installation. Because the coil and ignition module are built into the distributor, fewer external components and wiring connections are required compared to traditional systems.

What engines are HEI distributor kits compatible with?

HEI kits are commonly used with Chevy Small Block and Big Block engines, as well as other compatible applications. Always verify fitment for your specific engine before installation.

Do I need other components with an HEI kit?

HEI kits are designed as complete systems, but they are often paired with high-quality ignition wires and other supporting components to maximize performance and reliability.

Can I replace a points distributor with an HEI kit?

Yes, HEI distributor kits are a popular upgrade from points-style ignition systems. They provide improved reliability, reduced maintenance, and stronger spark output.

Are HEI distributors good for performance builds?

Yes, HEI distributors are widely used in both street and performance applications due to their durability, strong spark output, and ease of use.
