PRO MAG CAP HOLDDOWN, PN 8130, 8140

These retainers will securely hold the Pro-Mag's cap in place while locking the spark plug wires to the terminal.

PART# 8121MSD

Racing produces high winds and severe vibrations that can actually "whip" a plug wire causing it to fall off. With an MSD Wire Retainer this is impossible!

 PLEASE CHOOSE CAREFULLY, CLEARANCE ITEMS ARE NON-RETURNABLE
