Thinking about ordering a NX wet kit for my 95 Lt1......what all do I obsolutly have to get besides NGk tr6s???

 

00 at the end of this part number indicates a kit without a bottle, if you don't have a bottle you'll need one 05, 10 or 15 instead of 00 gives you the ki with 5, 10 or 15 lb.
What else do you need? If you plan on going above 100 hp then a bigger fuel pump is required. Another good thing to have is hotter spark with the ability to pull some timing and a window switch, Mallory Hyfire VI (#685) can give you all that.
