Yeah, I've read that thread 20 times. I am in no way shape or form interested in using ABS or PVC to make an intake tube. I want shiny metal pipe and preferably pre-fabbed for such installations.
PVC and ABS look like crap. I already have an intake tube made from plastic.
This friday I'll be going to autozone to find out if I can indeed make an intake tube out of the sections of piping they sell. I'll make sure to post all that I find.
I know... I said same general theory. Thought it would be helpful for references such as measurements.... I'm aware pvc looks like crap.
As for the subject of intakes to rid yourself of the stock air box, someone mentioned the kkm intake earlier in this thread.
Anyways, I have argued with several people on here several times who are convinced their butt dyno registers a huge change in horsepower and throttle response when they put on that overpriced air filter. I figured, meh, why argue, I'll buy one and put the truck on the dyno. Didn't feel like waiting till dyno time, and I wanted to see if there were any fuel mileage returns or if the filter somehow defied the laws of physics and did make some kind of noticeable change. Installed the KKM intake today, installation took about 5-10 minutes. Drove around for 20 minutes, various types of driving, in town, highway, WOT starts, accelerating from one speed to another.
Yeah, no change.... I'm sure you pick up a few horsepower at like 4300 rpm or some nonsense, but nothing in lower RPMs, and it would be nice if it picked up 1/2 a mpg... but I doubt the mileage will change that much. There was no change in "throttle response" (as if there would be anyways, physics people physics). Spend money on it if you want. I don't recommend it unless you have done quite a bit of other modification to your engine, induction system and exhaust.
I'll post up dyno numbers in a couple months if I can still get dyno time, and I saved the stock air box for comparison runs.
