MSD 8969 - Digital Programmable Window Switch for Coil Pack / Coil on Plug Ignitions

We highly recommend this MSD Window Switch for all Nitrous Applications. Missing a Shift or Bogging while the Nitrous System is activated can cause a huge intake backfire that can destroy Intakes, Throttle Bodies and other Engines parts as well as Hoods and other exterior parts. Be safe and install a window switch to prevent this from happening. This Window Switch is digital and requires no "pills" to program. It is Programmable from 200 to 15,000 RPM in increments of 100 RPM and designed to be used with Coil Packs or Coil On Plug Ignitions.
