Greetings all. I'm a long time lurker and first time poster.
I noticed weld spatter on the tips of these plugs when viewed under 40X magnification and assume it's from the laser welding process for attaching the iridium tip. All six of these plugs looked similar under magnification. The spatter isn't visible with the naked eye and look normal. I got these plugs from Napa and am 99.9% sure they're genuine. Is the spatter any cause for concern?
