Does any company offer a completely new whole intake manifold? I know Kinetix and Crawford offer plenums, but isn't that just the upper portion of the intake manifold?

 

None that I have seen yet.

 

LOOKS LIKE SSR Engineering has just come out with one there is a thread here somewhere about it check it out.

I believe that Esprit makes the lower half.......around 500-600??? I was calling around a couple of months ago when I went spend crazy with my car.

 

Not sure, but I think that Espirit piece is just a metal flange that goes between the lower and upper plenum. It essentially raises the stock upper plenum some. Personally, a Kinetix or Crawford would be a better, and cheaper way to go.
