Probably not, unless you have some reason to believe the current system is giving you an incomplete burn. The ignition system on the NSX is a bit weak, but very accurate. Unless you have modified the car significantly, it is probably up to the task.
On my motor, the spark was blowing out at about 5500 rpm or 12-14 psi, so we put a B&M booster on it and now it burns great.
