not worth the money. i have a set in my car and it really doesnt have any siginificant or noticable power gain. it's very decorative in the engine bay.
what nology incorporated is a built in capacitor on the wire insulation. therefore, what it does is maintain a constant output at all times. i believe that this set-up will be effective with a complete upgrade of the ignition system with plenty of engine internal upgrade or FI.
