Hey all, I had an intake installed. it's that cool looking Injen intake. Now this was the only upgrade I've made so far. I know I need an exhaust to help with the back pressure. Now the problem I'm having, is 3 times now, my car has stalled out. Once while slowing down at a stop sign. I had the clutch pressed, and the brake, as I slowed it stalled. The other day I was trying to pull out onto the highway, and as I made the turn slowly, it just died and I rolled into a gas station on the corner. Anyone have any special tips as to why this car keeps dying out like this and what I can do to fix it?

take off the intake. not a good first mod for the stock ecu, plus ur probably running worse than before. try getting other mods such as TBE, or utec, much more worth ur bang for each buck.

well, thanks drift, thats helpful, well no it's not, appreciate the input. Only problem with all that is I'm clueless when it comes to getting technical with a car. TBE, Utec, ain't got a clue. Just know the Utec is expensive, and i'm lost with TBE. All I'm looking to do is make a few simple upgrades to make it sound a little better.

1. Take off the intake. Most aftermarket intakes skew the MAF (Mass Air Flow) reading. Because of the different size of the intake, and air flow characteristics in the piping, the engine is receiving a different amount (could be more or most likely less) of air than what it thinks its receiving.

2. You can better hear the turbo spool by the doing the ever popular intake silencer removal - this maintains the stock intake (good up to gobs of power) and allows for the cool sounds you get from an aftermarket intake.

3. A good first mod is a TBE (Turbo Back Exhaust) with some form of engine management (EM). I would recommend starting with either the Cobb Accessport (AP) or an EcuTEK reflash. Both of these forms of engine management re-program the factory ECU for your mods. The result is a smooth delivery of power and a much more responsive car. With your level of experience I would shy away from a UTEC at the moment as it is more capable of letting you mess something up permanently.

Hopefully this gets you started, invest some more time researching and you'll find what you need. :D

Only problem with all that is I'm clueless when it comes to getting technical with a car.

Which is why you shouldn't have just stuck an intake on the thing. If you don't know anything, don't bolt things to your car.

The problem with the new intake is that it is a stupid mod for 99% of the people out there, because it will either do nothing, or it will do something the engine isn't tuned for, and thus mess things up. See: what is happening to your car now. Take it off and put the stock one back on. Then return it if you can, and sell it if you can't.

Since you just want to make it sound better, your best bet is to add a cat-back exhasut (CBE). A turbo-back exhaust (TBE) is a better mod in terms of power, but is more expensive and may be illegal for street use and/or cause you to flunk state inspections... depending on the exhaust you are getting, the state you are in, and so on. So I'd suggest that a total newbie like you not just jump in and get a TBE. A CBE is 50 state legal (as long as it isn't too loud) and emissions/inspection/warranty friendly. Plus, a CBE is half a TBE anyway, so you can always mod the rest of the exhaust later.

A simple tweak for more power is to get a Cobb AccessPort (AP) and re-flash the ECU with a Stage 1 map. This reprograms the computer that controls the engine to tweak various things and give you a bit more power. Just make sure you don't use Stage 2 maps unless you've installed the required mods first. This may void part of your warranty, however.

Just an update. Turns out, it helps to pop the hood and check to see if everything is alright. I got a little idea in my head that it may have a possible that they didn't tighten the sensor properly so I figured I'd look. Instead I discovered that the pipe's had come apart and I was sucking straight unfiltered air into the engine. Tightened it up and reconnected the pipe and haven't had any problems since.

Wow, holy un metered air batman.!

And did I read correctly that you had it installed, as in not by you.
You could have done it in 10 min with a little confidence .You could let a 12 year old with supervision of an adult do it. Sorry I had to. :) you would have gained more power with a 120 $ ebay down pipe than the 200 $ intake that’s my opinion and I’m sticking to it.

See the problem is the cai might make 5hp more but also might make your car run leaner. Will it blow up your car, well most likely not and you might gain 5hp-10hp.You can also make it lose power. But read some more you’ll understand .I will say one more thing to be careful about having air entering post maf.

http://www.dtcdigital.com/albums/sitepics/10001/injen-stiwrx.jpg Yea you read correctly, I had it installed by an Injen Dealer over by my house. Looked kind of complicated for me lol plus the way it had to be installed they had to remove the fender (guy said bumper but think he meant to say fender) and I certainly wasn't going to be scratching up my own sh** I would have been pissed

I had opened up the hood at the place n looked at it, everything was fine, problems started a few days later. Didn't dawn on me to check the connectors ya kno?

Now I actually did order this intake off Ebay. Then I realized the place I've always gone to for stuff was a dealer and I could have gotten it there for about the same price.

Your next mod should be a nice oil catch can if it isn't going to be any engine mgmt. I have the AEM short-ram off of my old wrx I traded in for the STi. It's sitting on my workbench where it will remain. Remeber to take that P.O.S. intake off of the car if (when) you plan to have any warranty work done.
Sorry to be so up-front.

I agree with the other posters.

But first off, an intake is a "bolt-on" part. This is something you could easily do yourself even if you've never worked on a car before. You dont even need to jack up the car to do this.

Now, I had a K&N Typhoon on my car, which I recently sold. Besides the "woosh" sound, I am not sure if it added any benefit to my AccessPort (AP) stage-1 mod.

My advice is:

- Sell that intake
- Get yourself and Accessport (go to the COBB website for more info)
- Go stage1 (if you can operate a microwave oven, you can operate an AP).

Drive with that for a while and see if you really need to get a TBE (turbo back exhaust replacement) which allows you to enter the world of high-boost stage2.

Oh, and if you dont have one yet, get a boost guage - it really can come in handy when doing mods (sort of a heart-rate monitor).

^^^^ :rolleyes: x100

Have you ever installed an injen intake? You cannot compare the ease of install of the typhoon to the injen. you DO have to jack up the car you DO have to remove some of plastic fender lining and it certainly takes longer then 10 minutes.


oh.. and another thing... I seriously doubt a single person in this thread has done before and after injen dyno comparisons on a stock sti (while checking AFRs) ...
Quit talking out your ass people. This intake probably works great on a stock sti.

i have a cai on my stock sti and ive had no problems at all the car pulls harder up top ive had it for a year with no problems

true, intakes are a waste of time and money. better off spending it towards mods that really do something for your car.

but, if your running a fmic then using the oem intake is not an option.

Bye Bye
