Best intake LS-1?

I know this has probably been asked before, but just wanted to know, i had thought that the only intake was a whsper lid, but there are several new more pricey ones. Is the best option a functional ram air?? Just wanted to shed some light

ram air would be good.

indeed

What is next to best beside Ram Air, which is a little pricey.

cold air intake maybe??? not too sure

slp sells a nice CAI for the ls1. its nice, made it fit on my 3.4 and it did wonders...
