Replaced my original NGK c7hsa plug, to a BRISK high perform=BETTER. Go to Amazon, type in Kymco performance plug, you will see 2, one yellow. They both are the same specs, only 1 comes, it is a drop in for ALL c7H plugs= Brisk said. IF you have a 9 or ? plug, CALL brisk in Texas, and they will match up your plug. The plug that comes is an upgrade to the pics.
