Nitrous Express Digital RPM Window Switch

Need to turn the nitrous on at a specific RPM and then shut it off again at a higher RPM level? The Nitrous Express Digital RPM Window Switch is designed to keep the nitrous from activating at low RPMs to maintain traction and will shut the nitrous off before hitting the rev limiter or over revving the engine. The simple two button programming allows you to quickly and easily increase or decrease high and low RPM settings in 100 RPM increments up to 9900. This is especially useful on an unprepared surface when the stakes are high!
