MSD Spark Plug Wire Mini Stripper Crimper Tool 3503
Building a custom spark plug wire set requires two operations at each wire end – stripping the jacket to the correct depth and crimping the terminal. The MSD 3503 handles both in a single compact tool purpose-built for 8.0-8.5mm spark plug wire, so you can complete a full set without hunting for a separate stripper.
