Opps, I left this off. For the Protege5

As anyone made a intake system that only replaces the piping and leaves the factory box?

The advantages of this is that it keeps the car somewhat quite and doesn't have the bad effects of any of the open filter systems.

I believe that this system is made for the Focus and is considered to be pretty good because it doesn't lose torque anywhere, and adds at the top.

 

Exactly that's what I'm talking about. It seems like some of the best intakes are those that utilize the stock box. Their are lots of advantages to these:

They don't increase noise that much
They don't hurt driveability as bad
They don't increase intake temperature
They don't suck in water

 

Best intakes utilize factory box .
Hurt driveability
Increase intake temperature Get a CAI
Suck water get an AEM bypass!
Open air filter bypass, bypass, bypass!
I am not trying to be negative but it sounds crazy.

 

Sounds like someone has fallen prey to marketing scams???? How much money have you spent in your intake system? And how much horsepower do you have to show for all of that flashy stuff?

CAI's will increase the intake piping by as much as 100% in some applications? Do you really think that's productive to helping the engine breath? Nope, it actually makes it harder for the engine to get air in most cases. That's why there are often times not any increases despite the fact that you're getting "cold air"

Short Ram's generally decrease the intake length (which is good) but they suck in hot air, which is bad. Which one gives the better improvement is going to depend on a lot of factors, that CAN'T be accounted for on a dyno.

What you need is a way to not increase the intake pipe length and still get cold air. That's the system that I'm describing.

 

I have spent $300 all told Injen, AEM, Tornado, and custom parts for air diversion. I would be happy to send you pics. The key is the scoop under the fender well that brings in cold air but also diverts water (even though I still have a Bypass. Also if you have taken apart the factory intake you would see the maze and length that the air has to travel.

 

In my opinion $300 is too much money for what you have. You can buy rebuilt turbos for under $300. Why should simple piping cost more then a turbo?

I've seen the stock intake system. The piece that I think would provide the largest advantage is replacing the snorkel that goes to the radiator with a different piece.

Make it shorter and larger. At the same time make the pipe between the airbox and throttle body larger and smoother.

Ice-Man makes this product that I'm describing for the Focus and I've emailed them to see if they have plans for a protege version. (yes, I know the focus doesn't have the same engine as we do, but the characteristics are very similar) Here's a write-up for the focus version: http://www.teamfocaljet.com/5_resour...ase/iceman.htm

As for my comment about hurting driveability. Most CAI's will increase hp(if they do anything), while losing a small amount of torque at low rpm. While this in itself isn't a problem, it does eventually lead to a problem, when you start adding more products that all reduce torque at low rpm, while adding high rpm hp. You will end up with a car that drives like a v-tech honduh. If I wanted that, then I would just buy one.

 

In case you have not checked how much intakes, bypass valves and other mods cost I suggest you do. Please go ahead and take a toilet paper roll and hook it up to your throttle body along with your $300 turbo and put it on your Focus. I am sure that will fall in the your price range for an intake.

 

You're too moody to continue this conversation with. You have to realize that not everyone shares your views on how to modify a car. Not everyone is going to be willing to shell out $300 for something that has never been shown to be worth that. No, 3hp is NOT worth $300, not for a daily driver anyway.

Does anyone else have any feedback on this?

 

lol at the last post by jcilforever. The thread should have ended right there, but i have something to say....i think that with all the electronics in/on the intake (sensors, MAF and so on) this type of fabrication may hurt performance. AEM and Injen spent many hours placing the sensors and other things. Their engineers know what they are doing and YOU don't. Quit being a cheap bastard and spend some money on a good product....there's plenty of them out there. Oh yeah....whats wrong with the engine having a little more growl to it. It sounds exactly the same to me when I'm droning down the highway at 80MPH.

You have any info or pics of your stereo. I have had good luck with Kenwood decks. Also which short shifter do you have, how much, and where?

 

Where on injen's site does it say that an engineer designed that system? You're fooling yourself if you think they pay an engineer's salary to make CAI's. And if they did, don't you think they would state that? I would.

They have several contact people, and there's only 1 technical person while there are 4 people working on sales/marketing.

Hmmm, sounds like a company that's more about marketing then "engineering".

You guys are all being suckered out of your hard earned money, or is it your Mom's money?

 

jmauld this is for you
OK, I know I should not say anything else , but this can not help being said I AM AN ENGINEER THE END

 

Oh no, you're an engineer! What a coincidence, me too! Unfortunately that doesn't tell you squat about what I do, or what I know. There are hundreds of different types of engineers, many of which know nothing about any other field of engineering (I'm not accusing you of that).

I however, am NOT an engineer that has a "Tornado Air System" blocking the air intake.... You should know better then that.

You guys have been really helpful and have offered invaluable technical explanations of why my idea is bad , but even so, I would like to here other opinions to the original question?

 

Exactly, and those type of systems shouldn't be confused with ANYTHING that's produced by AEM, INJEN or any other company that you see their name stuck on the side of your neighbors honda.

scroll to the bottom and read!!! At least they publish that the cold air intake was not the most powerful configuration. There is no way that anyone can deny that an engineer designed where the sensors plug in. All performance craving people know that to get more power you need two basic things: MORE FUEL AND MORE AIR!!! You also can't deny that the cooler air is the more dense it is and therefor you can get more in the cylinders. I hope your mod. does work and work well, but i also hope that it doesn't throw the check engine light up. Also don't assume that everyone here are chicldren. That was uncalled to say are you spending mommies money. C'mon, give us the benifit of the doubt and also grow up....
