BG Spark Plug Reconditioning Service

Fast, Dependable Service, Every time.

  1. BG reconditions your industrial precious metal electrode spark plugs using a 20+ step process that includes chemical cleaning, honing, gapping, repainting, new cylinder gasket, and complete testing.
  2. On the average, about 10% of the plugs returned are unsuitable for further use due to excessive electrode wear. These, if they are BG plugs, which “fall out” during inspection can be replaced with new plugs.
  3. Your cost of reconditioning is just a few dollars per plug (see price publication).
  4. Since about 90% of the plugs returned can be reconditioned, users find that their “average plug” cost is reduced substantially.
  5. Return plugs to your supplier or direct to factory (prepaid).
