I don't know, I'm still trying to figure that out...
A pipe is a pipe. Each of them will offer similar performance. Unless one is obviously a product of lesser quality.
For the 2000+ Eclipses, there are 2-3 different vendors that make intakes for us and they all over the same performance. So it's up to you if you want to spend a few more dollars to get a name brand pipe.

However, the MHP pipe is 3" in diameter, and I don't know what diameter the Injen pipe is. If the Injen pipe is 2.5" then it might offer better performance. Pipe diameter is a factor in where the extra power is made. And it has been said that 2.5" pipes offer better performance all around for the FS engines in our cars.
Just a thought.

I strongly recommend the AEM intake for our cars. I just installed one in a buddy's protege 5(same part number for our MP3s) and it was really well made. All of the parts fit perfectly and everything was finished well. Even though it isn't technically a "cold air intake" it might as well be, after the stock airbox and resonators are removed, we are left with a huge hole in the engine bay that goes straight to the ground under the car, this is where the filter of the AEM intake is located. Secondly, the piping is optimized by AEM to make the most power. During development, both short and long intake piping was dyno'd and the shorter piping made more power. Intakes like the Injen which has such a long pipe really hurt the low end of the power curve and the high end isn't that much better then on a shorter tube sucking hotter air. Temprature isn't everything, air velocity is just as important. The AEM is optimized for air velocity in the way the bends are shaped and the diameter of the intake tubing. AEM claims a dyno'd 9-10 HP from their intake. I don't work for AEM or profit in any way if you buy their product, I just really like it and it's what's going on my MP3.

Do you have any pictures of the AEM? And does the power come on mid rpm, or only on the top end? And, what size is the pipe? My only concern is what Racing Beat ran into with the short intake they had on the car they sent to Mazda.

the only way we will ever be able to tell which intake is better is some how get all the intakes in one location. get some one to do a couple dyno runs stock. put an intake on and do a couple dyno runs. put a different intake on do a couple of dyno runs. put on a different intake......ect.ect. you guys get the idea. this is the only way to find out what intake is better for what. expensive. but i plan to do it when i get some money. of course if the website or other poeple want to help in my area tha works also. Personally if it came down to looks i would take the MHP just cause i like the Carbon fiber look under the hood. IMO

Yep, that would cost some money. If there was enough interest, maybe we could get a magazine to spend the money for us...
Sport Compact Car did a story about different intakes for Honda's, dyno'd all of them, and printed the results.

From what I've heard if you really want a CAI, the Injen pipe might be better because it is either 2.5" or 2.75" pipe. A 3" pipe, in my opinion, is to big to get good usable power.
I've read that a 2.25" pipe gives you good torque down low and some real power down low, but as you hit the higher end of the rpm range it tapers off more towards stock. So, it makes power, but a little to low.
A 2.5" pipe makes good power from mid to high and is a good comprimise between a 3" pipe and 2.25".
A 3" pipe makes all it's power at the top, where it isn't as readibly usable as the 2.5". If the Injen is 2.75", then it'll be a good set-up for high end usable power (that would be my guess).
As for the AEM, they make good stuff, but they say they only offer what's best for the car, and then half the Hondas and Acuras have both the short ram and CAI. Some of those options are highlighted as to which is better, but most of them aren't. So, I wonder if the AEM really is the best option for our car. However, from what it sounds like, the AEM is practically a CAI, only instead of getting air from that hole in the engine compartment in the fender and moving the overflow resivoir, it sucks the air from just above the platsic under-body thing.
Who knows? Like freekwonder said, test them all, and let the dyno sort 'em out.

ChrisS is right, the AEMs filter sits just above the plastic underbody thing so it really isn't near anything that produces too much heat. The AEM seems to add power thoughout the band, from low to mid to high. Also, I don't like how long the injen pipe is, after the air travels from the bottom of the fender thought the engine bay and finally to the throttle body, the velocity has slowed down so much and has been heated by all of that metal piping. I'll get you guys pics of the AEM as soon as I can, probably tonight if possible. About Racing Beat saying that our ECUs not being able to handle the hotter air: I don't know where they got this. Right now, I'm running the stock intake with the resonator piping removed so it's sucking air right from behing the radiator and next to the engine, I have no problems and the car does pull harder then it did with all of that piping. Besides, have you ever looked at where the stock piping goes? the top piece that draws the air in from the front of the grill sits right on top of the exhaust manifold! try touching it after a few minutes of drving, it gets so hot that I can't keep my hand on it for very long....don't tell me THAT'S cool air!

try www.optauto.com they have em for just under $200 they are a great company to do business with.

Hey Section 8, thanks for all of the pointers on the AEM. I've been thinking about the AEM for quit some time now. Just a question though. I look at pictures of it on that website you posted, and I wonder where you hook up the MAF etc? There doesn't seem to be any location for that... Maybe I'm just stupid

DooMer_MP3: those pictures at options are just a generic pic...that's actually the AEM intake for the Honda Civic. The intake tubing for our MP3s come in two separate pieces, one goes before the MAF, one goes after. Again, I'll try to get you guys some pics as soon as I can. Sorry about the wait!

I installed MHP CAI the other night. It is definately a noticable improvement. And on top of the performance upgrade, the car makes a cool hissing noise on the outside at idle and when you hit the gas you can hear it suck in the air. Also about 4 grand at full throttle it sounds awesome. The install wasn;t too bad. I did it without instructions and now they have instuctions on their web page. I need to go and recheck everything this weekend. I was getting tired while installing it and started to get sloppy. It is a b**** to get those rubber fittings back together.
I am happy with it.

I installed an Injen CAI, a chip, header, full exhaust, and some NO2 last week and this car fly’s. I beat a Corvette Z06 in the mile and I also dusted several Mustangs and Camaro’s. This car is way underrated on horsepower. I think I am pulling about 300hp at the wheels!!

I know how you feel I filled up with high octane gas and I installed my InJen CAI and this car is fast as s***!!! I handed a Ferrari 360 Modena his ass last night. I was 12 car leingths ahead and let off for him to catch back up. I was having the time of my life.

I raced a Toyota Supra twin turbo about an hour ago and blew his doors off. He had two HKS turbos and NO2 along with a ton $$$ of other goodies and he could not even hang! How sad.

Hey,
I'm an idiot that bought a new Z28 Camode, 'cause I like being an idiot who likes crappy looking cars that everybody and their grandma has....It's so fast. I dragged a 550 Maranello, and I ran out of gas before I got across the intersection, but I had him when I rev'ed my out-dated v-8 motor based on 1920's technology. But, my car has history, even though it's built in Canada and won't be made after 2002.
And, I have no idea that nitrous is N20...I'll put NO2 becuase, like my name, I'm a Muscle Car Moron.
I have 300 horse power and I only spent way to much money, I only spent $23,000 for a car everybody else has...But, I'm cool 'cause of that...
