Sorry. I should have had more than a one word response, but it was late and I was on my way out.
I don't use the plug, so my statement was based on internet reports. I guess the issue was bad enough that they redesigned it (the plugs would develop cracks that would seep oil).
Are they any better, now? I've no idea.
Anyhow, a filter mag has much bigger, stronger magnets if you're into that.
