Don’t Toss That Spark Plug: How to Recycle Them & Get Paid

Posted: May 15, 2025


Don’t toss the old ones if you’re replacing your spark plugs! Some spark plugs contain valuable metals like platinum and iridium, which can be recycled for cash. Knowing which ones are worth saving and how to recycle them can put extra money in your pocket.

How to Identify Scrap-Worthy Spark Plugs

Not all spark plugs are created equal. To maximize your earnings, you need to know which types are worth recycling:

  • Platinum/Iridium Spark Plugs: These are the most valuable. Platinum and iridium are precious metals, making these plugs worth collecting.
  • Copper/Nickel Spark Plugs: Generally not worth recycling for their metal content. While they may have some scrap value, it is often too low to justify shipping or recycling them separately.
