E-MAG Auto Spark Plug Adapters Individual
Individual replacement auto plug adapters for E-MAG ignition installations. Used when replacing a single worn or damaged adapter without purchasing a full kit. Available in Short Reach (SR), Long Reach (LR), and Extra Long Reach (LRX) configurations to match your cylinder thread depth. Match adapter reach to your engine's cylinder bore depth.

Installation Note: Always install the spark plug into the adapter first (finger-tight and fully seated), then install the combined assembly into the engine. Torque to 18 ft/lb through the spark plug only, do NOT torque the adapter directly. Use anti-seize sparingly on the engine-side threads only.
