I recently replaced some spark plugs that probably had plenty of life left in them, and am now racked with guilt about wasting these precision manufactured devices coated with rare, precious iridium. OK, I might be exaggerating a bit but I'm still wondering what I'm supposed to do with them and throwing them away seems like a waste. I can think of three options:
- Put them back in the car and save the new ones for another 20-30k miles (if I even still have this car by then).
- Put them in a box in the garage with a bunch of other old stuff I don't need.
- Recycle them?
I don't think I've ever heard of taking spark plugs somewhere to recycle them but it seems logical that we'd want to do that given new plugs have electrodes made of platinum and iridium.
What do you all do w/ used plugs?
