Your scooter prob, came with a NGK cr7hsa plug, a BETTER plug is a Brisk NAOR14LGS. Go to Amazon and type in Kymco performance plugs. Two will show, 1 yellow, a yellow might not come, dont worry, they are the same. Its a drop in for ANY 7h plug, which is the heat level it takes. IF you doubt, call Brisk in Texas and ask them. If you have a 9 plug, they have a drop in for that one too=call.The plug that comes is an upgrade of the pics.
