Power Play Upgrade Plug and Play
As a Plug and Play upgrade you are releasing the rev limit and adding fuel and air for a better performing engine which gets you scootin down the road.
The NCY CDI does the job its intended too unlike various others sold online. Adding the NCY CDI along with a high performance coil completes the ignition mod. The UNI Dual Layer Air Filter along with main jets really get the GY6 engines where they need to be for the best overall performance.
