A high output capacitive discharge ignition throws electromagnetic interference off its power cables, and the usual complaint is radio static or an erratic gauge that appeared right after the ignition was installed. This capacitor mounts on the power feed and filters that interference out, and it also absorbs voltage and current spikes that could damage the box.

MSD 8830MSD EMI Noise Suppression Capacitor Features:

• 26 Kufd capacitor filters EMI from ignition power cables.
• Recommended for 7 and 8 Series ignition installations.
• Eliminates radio noise caused by the ignition system.
• Helps prevent damage from voltage and current surges.
