Anyone had this with plugs? Out the box, all good, nothing loose or mangled. Gapped, in the head, tighten down and 2 out of the 4 the ht poles and porcelin spin freely with finger pressure. Take them out again and not able to turn it. Back in and can turn it easily again! Thought I had imagined it. Wouldn't have been surprised if they were ngk's but they weren't they were denso 22's ! Hope we haven't got to watch for fake denso's now?
Bike ran fine with the dodgey plugs but wonder if it would if caught out in rain. Obviously binned and and replaced with good ones.

Thoughts?

Thanks, interesting reading. Bad news is non of the tell tale signs were present.
Guess I'll have to put it down to a bad batch.
