Not much, the cops will give you a better spark. The delet plates will help with the airflow and you won't have that lag in rpm till they open completely. You will see an increase with a good dyno tune.
The motion plates are what the plenum sits on. They are hooked to an actuator that opens when you accelerate opening the butterflies in the plates. The charged motion plates eliminate the actuator and are more wide open allowing more air into the engine and quicker acceleration by not having to wait for the butterflies to open. The coil on plug is the spark plug wire. The coil is built into the plug wire and when the wire is plugged in, it sits right on top of the spark plug. I hope this helps.
