Not much to say about them.
They are OEM bike plugs.

If you change your plugs annually, I wouldn't bother with the more expensive Iridium plugs. There are hotter plugs if you need them (and colder). But I find my Honda Shadow does find with the standard.

Not a bad price per plug, but you can get a cheaper substitute (just look up a cross reference part number).

My plugs did NOT come with the screw on caps, it was just the screw tips only.
(but my bike didn't use the caps either, so that was fine)

Product is exactly as advertised. No tricks, not a knock-off, cheap and quick shipping. Put them on my GS500 and got it running a lot better.

Best price on these, October 10, 2011

I needed these spark plugs for my 2003 Honda Shadow Spirit. Buying a bunch of these gave me the best price per plug, so I bought them here on Amazon. They worked just fine, haven't had any problems.
