intake questions...

[sundevilMP5]

hey everybody--

i'm planning on getting the injen CA...after all my baby deserves it...but i was wondering how much everybody paid and where they got it from...unfortunately tuner shops here in AZ are far and few...so i'm going online...so far i think the cheapest i found was at protege5online.com for like $230...did anybody get it cheaper anywhere else??

thanks in advance

 

[Sir Nuke]

not me....got it at Protege5Online too...

Try Auto Car parts.com, They had some for $218 or so a few months ago.

Like a few ppl on this site, i got the AEM short ram intake for like $235 installed. I've heard ppl comment on both but i figured not to follow the Injen crowd on intakes. Im not saying that Injen is bad because it not. Everyone has a different way to hook up their 5. U cant lose with either one.

Dude you paid to have it installed? Its just a few clamps & bolts

Bad Thing about Intake Q's

The Bad thing about asking questions about Intakes is that nobody has posted any dyno charts comparing the two (AEM VS. INJEN).

The AEM Owners love AEM and The Injen Owners Love Injen.
Somebody post a Dyno Already!:mad:

Personally I think that AEM & Injen are dead even. The AEM locates the filter within Inches of the Injen system, but it doesn't move the filter into the fender area. The AEM filter is low enough that all the hot air is going to rise up anyways. I think this whole cold air thing is a marketing device. You can't tell me that Injen system isn't sucking hot in.

That's what I'm Trying to say...

The only way we will ever know is to dyno the two intakes on the same car on the same day.

I do agree with you though...The intake piping is still inside the engine bay. The cold air coming into the intake will be heated by the time it reaches the throttle body.

Only a dyno will tell....

Not necessarily true. The air traveling throught the intake pipe is traveling at too high of a velocity for it to be greatly affected by the heat in the engine bay. And it is proven that all CAI's in general work better at getting the cold/ambient air into the engine. It's been proven on every intake review I've seen on every car they have been tested on. The AEM is positioned right next to the tranny and behind the radiator, which in our engine bay is very hot. The air right behind the foglamp should and probably is a lot cooler.

It has also been proven that the Short Ram intakes produce better torque at the lower end of the of the rev band but lose steam as the mid range approaches. CAI's lack the initial throttle feel that the Short Ram's have, but make up for it by producing more torque in the middle and upper end of the rev band. Of course the difference between the 2 is probably less than 3hp. And peak numbers don't determine a parts worth. So it's up to you. When you think about it, when cruising behind the wheel in your P5 or MP3, you're usually around 3500-4200 rpms. Well, that's where I'm at when I'm on the freeway or cruising on the streets.

AEM Dyno

I didn't know if anyone has come by these yet but here are the dyno's produced by AEM.
AEM 2.0 Dyno

AEM1.8 Dyno

Does Dyno Charts Do Not Look Convincing

Those dyno charts (that do not even look like they are real) are not that convincing.
The manufacturer will never say their product is not the best.

I prefer real life dyno charts. I have vast experience with NA engines and if there is something I have learned is never to take the manufacturers HP gains as even close to real life gains.

 

[Korey Chaos]

It was only like $10 to install and i had s*** to do so 20 minutes and 10 bucks was worth it. Is that alright?

Well until someone dynos both that is all we have to go by...(the manufacturers word) And at least AEM posted what they "found" on the protege's (be it truth or fiction) I haven't seen Injen post anything on the Protege.

We have the Injen on our car and have our data acquisition system running most of the time. We find the intake air temp from OBDII to be near ambient, or only a degree or two above. When parking the car after driving, there is noticable heat soak, and the temp at the sensor goes up 5-10 degrees. After running the engine for a minute or two, the temp drops back down. I agree some amount of heat will be transferred from the piping to the flowing air, but not a noticable amount. If we were to place a thermocouple at the throttle body, I doubt there would be much of an increase, particularly at high RPM. When you are driving at high RPM, you are typically driving fast enough the cool the engine bay through the passing airflow. Most heat in the engine bay will be generated while the car is stationary and running. If someone local would like to compare their AEM with ours, we could arrange a test.

Was shopping around the net today and found optauto.com... they have the injen there for $230, plus it looks like it now comes in red and blue ($238) as well. Previously there was only the ploished one with red soft parts. There wasn't a pic, which was disappointing, cause I'd like to see the blue one for my car.

 

[2002VividYellow]

Their price seems to go up & down on the Injen stuff..just a few weeks ago it was like $220 then $250 something.

I've ordered a fair amount of stuff from them, I'd recommend them.
