MSD Extreme Output GM HEI Distributor Cap with Coil Cover

The MSD Extreme Output GM HEI distributor cap is a replacement HEI distributor cap built to handle the high output of MSD's 20 Amp Extreme HEI Module. MSD designed and molded its own HEI cap, rotor and coil cover for this system. The cap works in high-output GM HEI ignition setups, including race and performance builds.

Key Features:

• MSD-molded HEI cap built for high-output ignition systems
• Coil cover included for a complete cap-mounted (coil-on-cap) HEI setup
• HEI-style terminals with a twist-lock design
• Fits MSD HEI Pro-Billet distributors and is designed to work with stock-style GM HEI distributors
• Backed by MSD's Manufacturer's Limited 1 Year Warranty
• Made in the USA

Pair it with the matching MSD Extreme Output HEI rotor for a complete high-output HEI distributor upgrade. The cap is a direct replacement that gives a worn or stock HEI cap more electrical strength and a clean look.
