Word. I think I'll just pick up the AEM here soon.. Would you happen to have a part number handy?

On my Si with the Injen intake, I eventually swapped to a Fujita filter. It was actually quite nice. Same design as the Apexi, but like $40 less. lol I'd get one of those if there was an acceptable metal tube intake for our cars..

I still own a legacy gt so the intake box is the same


If you take apart the box on the impreza or xv you will notice the bottom that goes into the fender has a hole that is blocked off on a legacy gt that hol is open and had a intake silencer on it


I was gonna drill that hole out on the impreza to get some more air flow

Ill try and take pictures later wife took the car.
But takemout your stock air box and look on the bottom there is a perfect circle that is block off.
On a legacy gt it is open and has a air silencer on it, i took this off my lgt to let more air in the intake


This would be the same for the impreza or xv 12+

I'm guessing it already is capable of more flow then required......

You talking about this hole:





This goes into this space:




I cut that hole out last summer and experimented with cold and warm air. Currently using warm air and it makes more of a impact mileage-wise (+3 mpg) despite losing some power. Cool air from the fender just burned more gas and not much zoom zoom with a CVT anyway so I'll take the better mileage instead. This was accomplished by using a 3" aluminum duct from Home Depot and a 3" to 2.something" exhaust pipe reducer to squeeze through that hole in the airbox.

Alright, gotta go cut the grass now

I find your +3mpg claim unrealistic. Cool air should produce more power and cut down the load.

I have a fender well intake on my other car in traffic I have seen iat climb 20f (insignificant really), and at speed it matches OAT. Under hood temps are warmer yes, but not that much warmer unless a at a dead stop

So that little hole going into the fender essentially just further grabs air (in addition to the grille scoop) at idle more than anything I'd assume? I really see no benefit of changing anything with that design short of using a bendy hose and routing it to the hole in the fog light panel (assuming you don't have them), thus forcing more air into the airbox at speed. Otherwise, it's not really doing much opening it up more or closing it out.. Correct?

I just removed the intake assembly on my Sport. I have no "hole" marked to the fender liner area from the factory. I will use a flashlight, but it definitely wasn't obviously marked.. Is it on the outside or the inside?

I doubt the FB-20 could suck enough air to justify any type of Ram air setup. I'd bet the engine bay doesn't get hot enough for there to be much difference at speed with cold air vs regular intake setup. I'd say a good filter will do as much as possible, and I'm not sure how much if any it'll help. If anything it'll give you a nice intake sound, which would be a huge improvement from a car that takes sound and tactile feedback away from motoring IMHO. I think the car runs better than it seems due to that fact. It seems very mundane and anemic. However, in town that anemia always gets me out in front at the dig under normal driving. With a little noise it would be a spirited drive. I just can't opt for anything sounding like a coffee can without a whine/ whistle and BOV. Otherwise I think I'd feel like a poser.

Side note: had a guy laughing at me in town once in the deuce just before the light turned green. He said car looked nice, sad I couldn't fix the rattling muffler. I shook my head and smiled, he was talking about the twin disk clutch chattering. So I try not to judge a car by its sound if I don't know what I'm talking about. I'd bet he felt the same way shortly after that too! ;-)

I posted this in the one other 12+ thread too, but this one has more viewers..

Inside the stock intake tubing, there's a little mesh insert between the intake filter and the long portion of the tubing holding the MAF. At least on mine, it's white plastic-ish mesh with grey material inside. I've gathered that it has something to do with the PZEV system. If you remove said mesh insert, will this mess anything up in the computer? These cars seem very touchy in the ECU department.

Yeah, cool does that and I tried it first. I'm talking about warm now. I switched to the warm air setup in late June. My last 12 fill ups average over 30mpg versus 27-something prior to that. See my fuelly.

Maybe or it could be a lot warmer if you have the duct wedged between the exhaust manifold and the muffler like this:

The service manual calls it a HC absorption filter. For it to have 'absorption' in the name, it must have charcoal in it.

Must be the black material behind the netting.. Would you say it was "necessary"? I wouldn't.. I'd imagine it's just some "green" crap that's not truly necessary.

You are correct.


It's when the car shut off UN burnt gas goes out the air box and this charcoal mesh thing get it.
That's why its a pzev

But does it do anything except "protect" the environment? IE, if I remove it, the car won't freak out, correct? lol

I don't think it will mess up anything the car, but not sure.
For sure its for pzev.

My Chevy sonic turbo had this also I took it out and did nothing at all.

So if removing the filter does nothing at all, then shouldn't those of us with PZEV cars just leave that extra carbon filter alone? Why remove it if removing it doesn't improve anything?

they are on the outside but underneath along the bottom and side of the headlight so you can't see them unless you get up close. they aren't noticeable unless you look for them.

I believe I purchased from the seller above, i got the longest one and just snipped off the excess (i think 24 is perfect measure, the one i had wires from both side to give you option on which side you want the wires to run which was convenient and just cut off one end). I think i got the 24inch so that it wraps along the bottom then up to the side towards the center of the grill.

buy a auto switch so that you dont have to splice into wiring (unless you dont mind) its a small box that hooks up to your battery and lights and once the car is turned on it stays on until you shut it off and the lights should stay on for 20 secs (walk me home feature) depends on the box (most have it). please note that some if not all these switch/box are cheaply made, ive gone through at least 2 of them already after several months. They have fuses but oddly enough the fuse doesnt go so i think its just the box/relay themselves. its easy to switch out but a pain to just take the time to do it.

I second that notion if there are no benefits.. what flow rate are those filters capable of? Might they be limiting to high flow air filters? A few cfm would be negligible and I'd rather promote clean air by leaving it alone until I can afford a Tesla lol.
