• NOTES
• NOTE¹: These high-performance items are not eligible for any further discounts or promotional pricing.

Convert your socket-style cap to a much stronger cap with HEI-style terminals. Not only do the HEI towers provide a locking connection, but you can hold the wires in place with the supplied retainer. With the retainer in place, there's no way a wire can pop off. The cap fits on a variety of MSD “Pro-Billet” distributors and can be used on many stock GM points-style distributors as well.
