Well I think totoherbs doesn't think intakes work just like headers don't work. All of these things can work, sometimes not in conjunction with the current ems. Headers can work on the STI, I have seen exact same STI car with and without headers and with headers make more hp and torque. I have this intake on my STI and I know there's a difference. Others may not believe it, but I really don't care because they are just opinions. I feel the difference mainly up top more where it breathes better. When I have a larger turbo that puts out more on top, I'm sure it will benefit even more from the intake. Not to mention this intake is baffled and can still pull in the cool air. This seems to be a good overall design.

To some of the the people in this forum, the only way believe anything is if one of the Super Scooby Doo experts on this forum gives it the thumbs up. You have to take opinions on this site with a grain of salt, even from some of the experts. Some upgrades are worthless, this upgrade is beneficial.

I was there, I saw the before & after dyno runs, and I now have a K&N Typhoon on order. FURTHERMORE: If someone will take me up on the bet, I will wager that this intake makes power. We can make a dyno appt and reset the ECU before the baseline, then reset it again before the run with the intake. If the intake doesn't make power, I pay for the dyno time - otherwise the loser pays. Any takers?

Never said that... I said they suck and some of the cheaply made ones realy suck. Not that they dont make power.

What I would like to see if a comparison between stock, just putting in a K&N (or similiar type) replacement panel filter and the Typhoon set-up. That way we can see how much HP the Typhoon system itself makes, as opposed to just changing the filter media.

I read through the Cobb Tuning tech articles and just decided to get the K&N panel filter.

Becarefull not to over oil it.. I know it seems like a small thing to worry about, but I have seen it done a few times.

jesus christ. The absolute misunderstanding of how the ECU works, how good this intake is and the doubting of the validity of Aaron's results in this thread astound me (although they don't really surprise me).

First of all:
There is NOT IAM factor in the STI ECU. There may be some other factor but IAM doesn't exist in the STI. All this talk of "ECU Reset is making the power" is absolute rubbish. His car would have to have been detonating BADLY and in limp mode for the ECU reset to cause an INCREASE in power. If anything, countless people have shown that the car's power will be decreased after a reset and it will rise run after run until it finds it det limit and backs off again.

I was one of the very early adopters of this intake and from the very start, I've said it makes more power than the stock intake without ****ing with the air/fuel trims. I have Tuna wideband permanently installed in my car so my judgements are qualified.

The single biggest restriction in the engine's intake path is the air filter. This is the MAIN reason intakes with large cone filters make power. By increasing the surface area of the filter, you reduce the restriction through it. This results in less pressure drop in the turbo inlet hose, which has lots of benefits for a turbocharger system.

VE is increased, intake charge temp is reduced, lag is reduced, etc etc.

To all the longtime naysayers:

This whole "agree to disagree" thing is such an overused phrase. How about this one:
You're stubborn and you'll never have a clue what you're talking about.

although the k&n filter media is less restrictive than the paper media, paper filters tend to have far more folds of paper so they end up being pretty similar in overal restriction.

It's been dyno tested way back in the past and the K&N filter (for stock airbox) didn't make any mentionable power.

Realy? I cant... I didnt know that. I have been showed to be wrong before... and I will say the same things now as I did then. Thanks for the info nhluhr.

Where is one single dyno showing that this "ecu trick" adds 10-20 hp on an sti? It makes no sence. What we need to see is a bone stock sti, dyno'd, then reset the ecu, dyno again and see what we get. Where is this dyno at? (truth is it loses about 10whp)

Lets see..... start out at 230whp, reset ecu and wow look I gained 20whp!!!! Maybe thats why my car has yet to run 12's stock

totoherbs - seams to be anti intake and i don't think would ever belive that they can make a difference.

People get in these ruts from reading more than actually doing and then all of a sudden these nice "intakes make no difference" staments start getting made into fact and is very hard to belive once one shows an increase in power.

As for this ecu trick....It does not add power to your car! It only makes it get back to it's max advance multiplier faster then driving it around. It's a trick to get back to the power you had before you reset the ecu, not add 10-20 hp to what you already have, So if the ecu was reset and the intake was put on and dyno'd before the ecu got a chance to get to the max multiplier, then guess what....Your power was from the intake, not the ecu, So reset the ecu, dyno the car, then do the reset trick and dyno the car again, what happens? I'm guessin that you would get more then the inital run cuz the ecu will be relearned at this time and not running off of 8 degrees advance. I'm dumb right? what do I know? Right?

The same things applies to the stock ECU. In stock cars, we've seen ECU resets result in up to 10hp losses which slowly add back in which each successive dyno pull. Again, this special reset just speeds along the process.

I think that pretty much sums up that the K&N intake kit makes power. Still don't belive me? read the whole thread about the reset...How the ECU trick does not add more power than you have.

So there is really only one way to get the non belivers to see that it makes more power...
1. dyno stock car, after it's been relearned right off the street.
2. reset ecu, dyno car.
3. do the reset trick, dyno again.
4. install intake, reset ecu, dyno car.
5. do the ecu trick with intake on, dyno car.
6. compare results and realize....it's ok to be wrong.

So to say that the power came from the ecu is wrong, when in fact it came from the intake, and guess what, it has more if it got that power on 8 degrees advance. I'm guessing that the 12whp was after the ecu relearned itself but i have no idea cuz I wasn't there the day they dyno'd the car to know exactly what happened.

I was waiting for someone who actually knows what they're talking about to speak up. Lots of stubborn people here who can't believe that there's an intake on the market that actually works! I just wish they made one that worked for the WRX, and not just the STi.

I was pondering this today. The STi and WRX stock intakes are almost completely identical. Anyone know for sure that the K&N will NOT work on a regular WRX? And if so, why exactly?

I'll take a stab -- hood shape is different so K&N shroud won't fit/work?

Question Veteran Input Sought

As far as I always knew, an intake didnt do anything for an STi. I used to have a 2.5RS before my STi and an intake definitely made a difference. Even before I added a Ganzflow CAI, I just changed to a K&N Panel Filter and even that made a small difference in top end power. I had convinced myself that an intake for an STi was a waste though after reading many comments. Based on the information on this thread, there may be newfound data to support that certain intakes may actually benefit the STi. I am always open to new ideas/discoveries. I was hoping some of the more heavyweight tuners/veterans would provide some more input on the issue. I look forward to any input. Please keep it to a friendly discussion and be open minded. I'll be watching carefully as this will affect my purchasing decision.

My guess is a possible MAF tube diameter/length difference? Heat shield dimensions?

I've swapped back and forth from stock to my APS 65mm intake twice, and feel confident that it does help. I switched back to help Trey at cobb troubleshoot an issue with the fact that i was seeing high EGT's on the new base map. just yesterday i put the aps back in, reset the use, and it felt noticeably better/stronger. I only expect that power to increase as the ecu relearns fuel.

The ECU shouldn't need to relearn fuel if the intake is properly designed as the ECU will get the same amount of air for the same MAF readings. This is what the K&N Typhoon appears to do.

You should be able to swap back and forth without any problems or learning required, the only difference will be increased power.

I thought that the APS 65mm was one of the good intakes that acted like the stock intake?

^ I suppose i didn't need to reset the ecu, but its always been my motto to do so if i changed anything. and yeah, the 65mm is one of the good intakes, as it doesn't throw off the maf and/or cause misreads.

When it comes to intakes, especially ones for the STi, the phrase, "once bitten, twice shy" might be the best way to explain the skepticism associated with the Typhoon. Don't get me wrong, I have great respect for Nick's (and other's) opinions but we've all heard the stories about how say, Apex'i (for example), offered a short ram with dyno-proven results but hardly anyone has it on their STi anymore.

Why? Car ran like poop after a while probably due to bad MAF readings. This isn't to say that the K&N will do the same thing but you can kind of get an idea of why there is a bit of skepticism even though the numbers look solid (I'm considering a Typhoon, too).
