    I think most of the kits for our cars use the 4 size. The nitrous lines that is. The blowdown tube is larger.

    AN sizes are in 1/16th's of an inch. (that's the outside diameter)

    Here's a link that shows some corresponding info for different AN sizes. It includes a picture at the top of the page, with different AN fittings shown to scale. That may help you confirm the size you need.

      Bigger size is louder and thicker but short clouds....
      Smaller size is quieter and thinner, but taller clouds
