You can damage the finwire tip and or cause the platinum coating to flake at the bend on the ground electrode. A quality plug should come “pre gapped” for the application. Always check the gap before installing, if they are not what you want or extremely close (you have a daily driver not a race truck) then return them for another that is what you want. Getting bounced around or dropped at the parts store can close the gap if the ground electrode is hit. It doesn’t take much to change .001”.</blockquote>
