Need a little help as I continue my install. The NX nitrous noid has three ports - marked "in", "out" & "P". What is the "P" for? :confused:

 

P is for the purge system.

 

I was using one of the manifolds that came in the kit at the inlet side of the noid and attching the purge noid and nitrous line. Is it better to use the "P" port or is it OK to leave purge noid at the inlet side? Thanks for the help!!! :confused:

 

I looked at my system & I reviewed the instructions. The P port (the other IN port) is plugged if a purge valve is not going to be used. You have the installation correct. The purge valve is run of the inlet pipe of the main feed line. The P port on the nitrous noid is plugged.

 

If you do use the purge ... set it up to look cool ...
