So pull out the wire, put degreaser the the Spark Plug then say like taking a wet towel and cleaning it then pull it out after twisting it and then put the new one on right, and put degreaser on the new plug too? Or could i just clean around that area, then take out the wire, twist out the plug, put degreaser on the new plugs and let it dry or wipe it a little, then put it on? Also this is all for the back since we are doing it blind.
