Just put a payment on a Neon R/T Magnum intake manifold today!! Going to be picking it up in a week or so and putting it on my SXT. I'm sure I will be able to figure it out with a few friends' help, but I know some of you have done this before and maybe you could save me from going in blind.

Now, I know it's not just a bolt off/bolt on mod. I know I'm going to have to get a gasket and such, but my real questions lie within the "butterflies."

What are "butterflies," and what do they do? Is it just another name for the secondary breathers?
My other question is that I've seen a lot of talk about using an RPM switch to the "butterflies." Is that how you recommend do it? It would be the sh** if one of you could describe the whole swap as much as you can if it wouldn't be any trouble.

Thanks a million!
