You may be using Spectre's corrugated plastic tubing. I am, and I have it because it's extremely cheap. However, I strongly recommend that you change your setup to this expensive stuff with a couple extras. It doesn't absorb heat from the engine like metal piping does, it won't kink, and it's aircraft-grade stuff that NASCAR, ASA, and SCCA guys use. Actually, NASCAR and other organizations use the single-ply tubing for brake ducting, but double-ply is better because it's smoother on the inside.

You can only choose between red, blue, or orange. I think that since the 3" tubing is marked as YELLOW, choosing the colors may not make a difference. The pictures on that site are terrible, so let's look to Amazon for $40-higher prices but with more pictures.

I recommend the 3" ducting since it's easiest to make it work. This stuff is awesome since you just put it on a metal or plastic coupler/throttle body/MAF sensor and tighten it with a hose clamp. It is its own coupler! The price may be a turn-off, but you only need 2-3 feet. With a group buy, we could be set. Do we have enough faith in the forum to do a group buy, and who is normally in charge?
Also, I highly recommend getting a 3" velocity stack adapter.

With this, clamp the tubing onto the 3" end and put on an air filter with a 6" flange. Here is a list of 6" flange air filters from K&N, AEM, and Amsoil:
K&N
6" long
8" long
10" long
18" long <- Yes, that's a foot and a half of filtering madness!
AEM
9" long

Use the following part numbers:
EaAU6065 - 6.5" long
EaAU6075 - 7.5" long
EaAU6080 - 8" long
Ultimately, this gives you a huge filter, a velocity stack to increase air intake speed, very smooth intake tubing at under $7 per foot (at length), and you should get a few more HP out of this setup than with plastic Spectre tubing. Also, this intake tubing does not absorb engine bay heat like metal piping does. It's in my opinion a superior intake. You will need a small metal/plastic coupler for your vacuum/crank vent/air temp sensor, but I don't have a link for that right now.
