^ with the equipment that companies like AEM & INJEN have at their disposal, it really is a one day process. The majority of the time, they borrow someone's car for an afternoon and that's enough time for them to make an intake for it! Rather than building a system from scratch, why not start with an ebay intake and modify it? You could lengthen the pipe to have it collect air from somewhere colder, or you could easily fabricate your own heatshield around it..

i'm not here to argue with you, but i feel you're giving these guys too much credit for their hot air intakes. these intakes are for the "sound" crowd. not the horsepower crowd.
"there IS something that goes into designing an intake other than just bending pipes, slapping a filter on it, and calling it a day." their name. that's it.
"btw, these are not products that require multi-million dollar ad/marketing campaigns" yes they do. that's why you consider these name brands.
none of these are carb exempt, so not much R&D.

as i can't attest to having any behind-the-scenes knowledge, i'm just speaking from personal observation and a few things i picked up along the way, nothing more.
and yes, these SRI's are indeed for the "sound" crowd. that's why i have the joe z pipe.

another side note....these things are super cheap for a reason: mainly that the maf sensor port is hastily cobbled together. I've purchased and hacked up 3 different intakes that were all very similar in apperance. Only 1 of them works as intended without throwing a cel code.
All three intakes are the same length and diameter (meausured with digital calipers) but some of the maf ports have differences in the welds and dont allow proper seating, I think.
At first i thought it was because the aftermarket tubes were slightly larger causing the maf sensor to run past its allowed values for air. But no, the aftermarket pipes are SMALLER than the stock intake at the maf port. SMALLER!!!! only by .07 of an inch but still smaller. There is also absolutely no way air was slipping past the sensor anywhere else. I quintuple x2 checked it.
So...any cel you get will probably be a lean code caused by improper maf sensor seating, angle, or location on these cheaper intakes.

my work firewall blocks ebay.
I think there are basically two types. One type has a widened bell like mouth into a larger diameter filter. I dont recall ever having problems with that one.
The others were just a straight 3 inch tube all the way.
It's really kinda luck of the draw IMO on how well the guy welded the maf sensor regardless of design.

Also, I've realized that one of my intakes doesnt allow for a proper vacuum tube connection. It places it far too far back so that the hose doesnt fit JUST right causing a *slight* kink in the tube.
I kept getting these p0101 errors codes over and over and NOTHING seemed out of place. But I suppose when the engine pivots on its mount EVER so slighty, that *slight* kink becomes a BIG kink and enough of a problem to throw the code.
Since I've replaced the hose with a longer one from the auto store, I havent had any codes come back. Keep that in mind.
