the red piping is the WRX pieces, the chrome ones are the spectre pieces in order to make it all work together [i noticed a improvement on low end torque]

An improvement in low end torque? I have only heard of low end losses with just about any CAI setup that loses the factory airbox. Anyone have insight into a low end torque gain with a CAI? I would love to get my low end back and keep my high end gains with my CAI if its a matter of setup or addition of something. Looks good, BTW. suprisingly clean for a franken-intake.

Is the filter itself in sitting in the fender well?
What air does it pull from? Engine or outside (I see fender holes to the engine bay)?

You've got a bend on either side of the MAF .. and the piping is sized for a different MAF. Two wrongs don't make a right. Even most WRX owners who've read anything on this site know better than to throw those on a WRX due to the way it screws up the MAF reading.

Sell the WRX intake and buy a cheap intake from Ebay and a MAF adapter. Trying new things is cool.. but throwing stuff together and making something bad work just to be different isn't.

Dont listen to them i bet that runs fine on the 2.5i. I agree too many bends witch probably affect the sound and performance slightly but its original. Good DIY.

lets see, if AEM tested thier intakes on a WRX, then i assuming it WORKS! [isn't that why major companies send thousands of dollars on R&D for?] (the intake i have is a TRUE AEM piece, i'll use that before i use any cheapo intake off ebay, the other pieces are from spectra)

oh yeah, and if you look at ANY CAI for a WRX/STi, you know damn well there will be bends before and after the MAF sensor to make it work for the fender opening! the only intake that does NOT have a bend is a Short Ram style intake!

i have yet to throw any CEL's in my car from the mods i've done. so apparently, i must be doing some thing right....

i might take out the WRX MAF pipe and swap over to a spectra 4" maf pipe... [which will take 2 bends out of the piping ]

In general, try to keep all piping about the same diameter. Or at least start big then go smaller and not back and forth big and small. It wont matter that much just telling whats optimal.

Nothing you slap on there is going to cause a CEL unless u mess with the MAF itself or the MAP. Go ahead and mess with different setups. I tried like 4 or 5.

i've messed with the MAF it self and throw a couple of codes, nothing like having a OBD2 scaner handy

hes a happy dude, besides thats an obvious and poorly masked attempt to change the subject. but regardless, the WRX and 2.5i intakes being the same diamater hardly make the intake design similar. One being forced induction makes so many other variables relevant that you cant even compare the two... its apples and pork chops.

I agreee with this. I also agree with the OP that he got the WRX intake "to work" on our NA which is what he was trying to do. It "functions" as an intake and probably improves top end air flow over stock. But no, your right its not an optimal setup.
