I just bought 4 DENSO IKH20TT spark plugs over the Internet.
One of them has a dent in the thread near the bottom (last photo) and its tip about the middle is a little uneven (first photo). (See photos in full size in order to understand what am I talking about by right clicking on them and selecting "View Image").
Thanks in advance for your time!

- Do these things indicate any problem about the spark plug?
- Also there are a few left overs from the plastic cover in the thread (tiny plastic pieces). (If you pay attention you can see them in all 4 photos.) Should I remove them before installation. Would they cause any problem if they stay there?
Thanks in advance for your time!
