This retainer holds the coil wire boot securely in the coil tower. The lower portion snaps around the coil body under the flange and is held in place with a nylon tie wrap, keeping the wire from working loose under vibration.
MSD 8217 Fitment:
- Fits most MSD Blaster coils except the Blaster 3.
- Fits most aftermarket canister style coils.
- Snaps around the coil body under the flange and secures with a nylon tie wrap.
- There is nothing worse than losing a race or not making it up a hill due to a coil wire slipping off. To make your coil wire connection full-proof, MSD offers this Coil Wire Retainer. The Retainer is molded from Rynite and features a ''hood'' that pushes down on the coil wire boot and secures it in place. Fits all Blaster Coils (except High Vibration and the Blaster-3) and will work with most other aftermarket canister coils.
