I am helping a friend install a nx wet kit on his mustang and he bought the kit used so he doesnt have the instructions where can I find them and a list of parts he might need like the piece that you attach to the fuel rail for the nitrous kit?
i would go to the website and you should be able to get the directions off of there. I needed them for my ZEX nitrous kit, and they had .pdf files to print on the site.
I agree goto the web site. If you cant find anything goto your local speed shop (if they carry NX products) and see if they can copy directions from what they have in stock.
