Also another pointer
( When coupled with K&N Air Filters we saw a 7RWHP gain on a 2002 C240! )

1 - $110 for slightly bent aluminum tubing seems a bit unreasonable
2 + The heat conduction of aluminum versus insulation of the plastic tubing is not much of an issue. Either way you're going to reach about the same steady state temperature rather quickly and given that most CAI systems use aluminum or SS tubing, I wouldn't be too worried about that.
3 + That they are the same diameter isn't really the issue here, rather the fluid dynamics of the flow through the tube. The ribbing/accordion texture creates a more turbulent boundary layer that will restrict the flow more than a smooth tube.

As for the Kevlar pieces, they don't fit quite right on the sedan I guess. Wavey pointed that out to me.
question is, does the tubes heat up after a 1 hr drive. since it IS metal.
That's a pic of the tubes. It is not CF/Kevlar, but more of a sound suppression Kevlar type material. It looks like cloth wrapped over a spring with black rubber on the outside of it.
I think you are thinking that it is a smooth CF piece, which it isn't. It's hard to describe. I'll try and get some detailed pics up soon.

We do offer the KN filters with the tubes, link is in the first post.
I still get $76.00 with shipping...not $60.00
