Edelbrock RPM Activation Window Switch

Edelbrock's RPM Activation Switch will make sure that you do not inject nitrous into your motor at too low or high an RPM. It's very important to make sure that you shut off your nitrous before your RPM Rev limiter as the way most work is they cycle the ignition spark, and if you're injecting nitrous into the cylinder while it is not fired in a cycle, catostrophic engine damage could result. This all-digital switch can activate and deactivate the nitrous system at any desired rpm. Adjustments are made with the touch of a button — no chips to hassle with! Application: Universal
