We’ve had an email from Scott, asking:

Is there any use for old sparkplugs?

As someone who barely knows what a sparkplug looks like let alone does, I’m not really in a position to answer this question. Google tells me that they can be cleaned up again but it’s not recommended (although disclaimer: all the people talking about it are performance/engine obsessives, so they might be pushing for more than the average person).

Does anyone else know if they can be revamp and reused?

Or what about other reuses for them? Anyone incorporated them into any other creations?

And what about recycling? Can they be recycled for their component parts and if so, where/how?
