I have a question about the icebox. Will one from a GSR fit onto a 98 LS without any problems or modifications? I'm asking because on the Comptech Website, they have two different ones....one for LS/GS/ITR and one for GSR.
Is there a difference in intake size?

 

they are the same if you are using the OEM intake tube.
Only the "bellow"- the 1.5" high, 2.5" diameter rubber thingie (sp?) of the sets are different.
One is angled while the other isn't.
Actually, since I used my OEM tube, I believe that I didn't even use that part.

 

when you are referring to OEM intake tube, I'm assuming you are talking about the piece that connects to the intake manifold. I don't know what a "bellow" is though. Is that something found on the icebox or is it on my existing OEM intake box?

 

the bellow comes with the Icebox among other things. And yes, I was talking about the tube to the intake manifold.

Per instructions, I am pretty sure they call it the bellow. and that is the only difference between the two sets.
