Nitrous Express Digital RPM Window Switch
The NX Digital RPM Window Switch keeps the nitrous from activating at low RPMs and shuts off the nitrous before you over rev and/or hit a rev-limiter.
This new Digital design allows you to set high and low RPMs quickly and easily without changing pills or chips.
This Window Switch will only work in vehicles which provide a 4,6, or 8 Cylinder input.
If you have a vehicle with coil on plug or any vehicle that does not have a distributer please contact us before ordering.
