An engine plug holds the starter in place on the engine as you are preparing for launch. When you launch, the plug helps the engine build up pressure before expelling it.
Our engine plugs come in packs of 20 each. The yellow plugs are suitable for 1/2A6, A8 and B4 standard engines and magenta plugs are recommended for B6 and C6 standard engines.
