I aint hatin on AEM its just that the Dyno dont lie! Dyno picks are at the bottom!

http://performance.clubrsx.com/intaketest2.html

there is the direct link to where the pics started from.

If you look at http://performance.clubrsx.com/intaketest25.html you will see that when the car is warmed up the AEM loses about 6 hp! Injen blows AEM out of the water, not only does it outright perform better it dosent suffer from a warm engin bay!

Ok I see you guys talking about AEM, Injen, and knock off ebay ones. How about those DC Sports short ram? (dont know if they sell them anymore or not) Anyone ever had one?

ok, since no one seems to have the time or energy to click a link or do any research here are the dyno results from the first test:

Injen
Run #1 - 186.6hp & 133.5lbs - Dyno Chart
Run #2 - 186.7hp & 133.4lbs - Dyno Chart
Run #3 - 185.1hp & 130.9lbs - Dyno Chart
Run #4 - 185.3hp & 130.7lbs - Dyno Chart
Run #5 - 186.1hp & 131.6lbs - Dyno Chart
Run #6 - 182.4hp & 129.2lbs - Dyno Chart
Run #7 - 183.7hp & 130.1lbs - Dyno Chart

Injen Average = 185.128hp & 131.343lbs

AEM Cold Air
Run #1 - 185.5hp & 133.1lbs - Dyno Chart
Run #2 - 183.8hp & 130.1lbs - Dyno Chart
Run #3 - 185.3hp & 131.0lbs - Dyno Chart
Run #4 - 184.3hp & 130.8lbs - Dyno Chart
Run #5 - 184.7hp & 130.3lbs - Dyno Chart
Run #6 - 184.2hp & 130.9lbs - Dyno Chart
Run #7 - 184.5hp & 130.6lbs - Dyno Chart

AEM Cold Air Average = 184.571hp & 130.971lbs

AEM Short Ram
Run #1 - 184.4hp & 133.2lbs - Dyno Chart
Run #2 - 183.9hp & 131.8lbs - Dyno Chart
Run #3 - 183.7hp & 131.1lbs - Dyno Chart
Run #4 - 184.0hp & 130.8lbs - Dyno Chart
Run #5 - 183.3hp & 131.0lbs - Dyno Chart
Run #6 - 183.1hp & 131.1lbs - Dyno Chart
Run #7 - 184.1hp & 130.7lbs - Dyno Chart

AEM Short Ram Average = 183.785hp & 131.386lbs


And now the results with the heat test:
Injen Cold Air
Run #1 - 98.2hp & 129.9lbs - Aborted Run - Problem with tach signal
Run #2 - 123.7hp & 128.2lbs - Aborted Run - Problem with tach signal
Run #3 - 194.7hp & 135.7lbs - 5 minute cool down before run
Run #4 - 194.3hp & 135.5lbs - No cool down, car ran for 10 minutes before dyno run

Injen 2 Run Average = 194.5hp & 135.6lbs - Dyno Chart

AEM V2
Run #1 - 192.0hp & 137.1lbs - 30 minute cool down before run
Run #2 - 192.1hp & 137.7lbs - 5 minute cool down
Run #3 - 191.4hp & 137.0lbs - 5 minute cool down
Run #4 - 185.7hp & 135.2lbs - No cool down, car ran for 10 minutes before dyno run

AEM V2 Average = 190.3hp & 136.75lbs - Dyno Chart


I dont know why there is such a huge difference in the warm engine test, but all i can think of is the AEM intake tends to retain or absorb more heat than the Ingen. So, in a huge round aboot the answer to your question of the DC Sports SRI is, well, its an SRI and you will get nominal gains, just not as much as you will with the CAI.

A note on the AEM V2...
Ok, many of you may not know, but the concept behind the AEM V2 is to make the air travel faster. They are trying to take advantage of the Venturi effect. "The Venturi effect is a special case of Bernoulli's principle, in the case of fluid or air flow through a tube or pipe with a constriction in it. The fluid must speed up in the restriction, reducing its pressure and producing a partial vacuum via the Bernoulli effect. It is named after the Italian physicist Giovanni Battista Venturi.

The reduction in pressure in the constriction is a result of conservation of energy: the fluid (or gas) gains kinetic energy as it enters the constriction, and that energy is supplied by a pressure gradient force from behind. The pressure gradient reduces the pressure in the constriction, in reaction to the acceleration. Likewise, as the fluid leaves the constriction, it is slowed by a pressure gradient force that raises the pressure back to the ambient level. It is also traditionally used as an explanation as to how a wing generates lift to allow an airplane to fly. However, this simple theory of lift is now regarded as incorrect." - Answer.com

In the end the dyno results show that there is little benefit in how AEM has applied this principal. I would have to guess that there is not enough of a size difference in the two pipes to take full advantage of the venturi effect. Furthermore, i presume going from a 3" pipe to a 2.5" pipe would work better, or maybe even from 3.5" to 2.5" piping. Any other questions? Got any data to prove me wrong?

Dude just get a cheap ebay one and slap on a K&N. Trust me, especially using short ram, you are not gonna notice a difference between AEM, ebay, or any other brand. A pipe and a filter is all it is. Do yourself a favor and save the money in this case. If you've got the money go for it, if not, a pipe is a pipe and a filter is a filter. We're talking about a small difference here.

BTW I tried a search on dc sports short ram and nothing came up. Everyone else was asking about short rams and getting anwsers so I thought I would ask about the Dc Sports one since I was bidding on it on ebay. Was a simple "has anyone had this one?" question.
And by the reponses here I take it no one has.

In theory yes, however in real world the air doesn't stay in the tube long enough to heat up so that too is a waste of money.
ORIGINAL: addiction2bass

only thing that might boost performance alittle is to wrap the intake tube with some insulating material to block out the engine heat alittle beter.
