This is the first time I am attempting to change my stock plugs to new Denso Double Platinum. Removed #1 plug, vacuum some debris out & replaced it no problem. Removed #2, looked down the hole and there was a small piece of paper (looks like it was of those tags that are usually wrapped around wires. It was approximately 1/4" x 1/4" in size). I tried to vacuum it out, but unsuccessful. It fell down. Is this something to be concerned about?? My first guess is that it will burn off.
