MSD 8445 MSD Cap-A-Dapt Kit

If the new Pro-Cap doesn't work on your application, these MSD Cap-A-Dapts will do the trick. The MSD Cap-A-Dapt adapts a large, Ford style cap onto your MSD distributor. This large cap spaces the spark plug terminals farther apart which lessens the chances of cross-fire and ionization occurring. Spark plug-style terminals are used on the cap for tight connections that will not vibrate loose.

The Cap-A-Dapts will install on most MSD Pro-Billet Distributors (except the Ford FE).
Kits are supplied with a high quality cap with brass terminals, rotor and cap spacer.
