This is the ignition coil used for the newer Chinese made engines on the Evo 2X. It will not fit on the older, Italian Active engines that the original Evo 2X's came with.

If you have an engine with a green engine cover on it, that means you have an original Active engine and need to order the Active version of the coil found here: http://www.neoscooters.com/proddetail.asp?prod=Evo2x_Ignition_Coil
