So, I was wondering how you feel about these plugs? Several of my kits have come with them, and they seem alot better in quality than the LD Z8C plugs, I currently have an old NGK B6hs(from last year, cleaned it with a wire brush) but I think the GM(great master, not general motors 
)plug seems to fire better, I plan on getting a b5hs from the auto part store, generally I run the 5hs in winter because it's a hotter plug, then I'll run the 6hs in spring and summer. Also, any other plugs you've used and would recommend(prefer something same length and thread as the stock plug) let me know!
