I'm about to install a set of NGK BKR7E copper sparkplugs in my wrx and while I was gapping them i used pliers to decrease the gapping and it left indentations on the sparkplugs. I was just wondering is this ok to be used or should I buy another set?
PS: I got my coilpacks in the mail but waiting to see if the proper gapped sparkplugs will do the trick.
