I'm not getting any replies in the Nitrous forumn, so I'll try asking here.

Does anyone know where I can find an "unused vacuum fitting coming off the intake manifold plenum"? Pics would be especially helpful.

Thanks

 

I'm assuming that quote is from the instruction manual. There are not any "unused" vacuum fittings off the fourth gen manifolds that I know of so there are a few options. One would be to splice two other vacuum lines together, leaving an "unused" fitting for your nitrous. Don't go out and do this or anything, but you could also drill a hole and make your own fitting, but I'd wait to hear from someone else who's done a nitrous installation before you go and drill into your manifold.

 

Yeah that is from the instruction manual. I need to know if it would be alright to use a tee and splice into one of the intake lines. Anyone know if this is the way to do it?
