VST's new ignition system upgrade provides a noticeable increase in spark duration that you can feel. The kit is popular on both turbocharged and non turbocharged engines. Can be especially helpful in preventing mis-fire in high boost applications such as those produced by an ECU upgrade. The VST REV modules attach directly to the top of the stock coils, they do not replace the coils. If you are currently experiencing mis-fires, a fresh set of plugs may solve the problem or you may need to replace the coils. For more info, please visit
