MSD 8217 Coil Wire Hold-Down Retainer for Canister Style Ignition Coils

The MSD 8217 Coil Wire Hold-Down is a purpose-built retainer designed to keep the high-tension coil wire boot firmly seated in canister-style ignition coils. A loose or popping coil wire can cause misfires, hard starts, and ignition failure — this simple but effective retainer eliminates that problem.

Key Features:

• Securely holds the coil wire boot in place within the coil tower
• Lower portion snaps around the coil body beneath the flange for a positive fit
• Secured with an included nylon tie wrap for vibration resistance
• Compatible with most MSD Blaster Coils (except the Blaster 3)
• Fits most aftermarket canister-type ignition coils
• Constructed from durable black plastic
• Emissions compliant — legal for use on emissions-controlled, non-emissions, and race-only vehicles

The MSD 8217 is an easy, low-cost solution to prevent coil wire separation on the street, strip, or water. Sold individually.
