AEM Short RAM Intake vs. AEM CAI

[Sponjah]

A buddy of mine told me that the AEM short ram intake is better than the CAI from AEM because it has less bends in it. Is this true? I thought CAI was the better of the two. Is there a major difference in hp/torque between the two? Thank you for your time.

AEM CAI > AEM SRI.

CAI pulls in cooler air, SRI pulls in warmer air. cooler air = better. nuff said. :cool:

In serious all motor builds, I favor the short ram because it keeps air velocity up under high RPM. For everything else, I recommend the CAI.

I recommend the CAI also that is unless youre paranoid of water getting into your engine then go with the SRI. But you living in Cali you wont have a problem with it.
Dont anyone even tell me about dumb little thing to put on CAI to stop water because water has to pas through it first before it closes off. Plus who wants a flange in a high flow pipe?
If you get CAI and your area has literally flooded just remove the CAI and put the filter directly on the intake.

i've used both on my '97 Civic EX, and both gave the same "power" gains ... if there were any. :) The only difference I noticed was that when it was 85 degrees or hotter outside, the car felt more consistent with the CAI.

i have the cai on my civic i agree that theres isnt much difference in hp gained from the sri vs. cai. my car is a single cam so it really didnt matter which i used....i wasnt going to get mu ch power off it anyway. if u have a dohc, i would definitely go with the cai. ull see more difference than the sri. if u only have a single, it wont make much difference which u choose. might as well get the sri...its cheaper.

Courtesy of 'Hondatuning' magazine (meaning both were tested on hondas):

AEM CAI: +20.7 HP, +5.3 lb-ft or torque

AEM SRI: +5.4 HP, +4.9 lb of torque


...self explanitory.

That must have been on a very built car to get those #s. What car was it exactly?

I'm not a fan of the valve either, but the water does not have to hit the valve to activate. It works on a pressure drop principal. The intake will suck air from wherever its easiest. If the pipe becomes submerged, it will suck air in from the valve.

YEA..NO SHIT....20 HP FROM A CAI ON WHAT CAR??

[OPAKRACING]

haha, i just read the article before the data, and it said it was on the RSX.

Stock?!?!

I have a hard time believing those large #s. What issue/page?

Lol, well I had one on and took it off ;)

hahaha 20.7hp.
riiiiiiiiiight, OBD3 is all of a sudden a modders dream.

[OPAKRACING]

the magazine said that. lol, i doubt that they're lieing.

I thought intakes HP gains where based on a percentage? and i thought cooler air means more dense air = more air, period! Hot air intake pipes means less air, doesnt it? it is said that for every 10 degree F, means 1% gains or loss in HP? Shorter intakes, mean higher volocity, i think its more like tube diameter, the smaller the higher the volocity, of course if you go to small, then it becomes restrictive...The problem with small dia. piping short or long is that you loose volume, without volume you loose torque....in most cases with one streight small diameter, you will get peek HP but no torque. So you loose HP and torque in the lower and mid range, but kick A$$ in the higher range, because the air is supplied quicker to your high reving engine.....one more thing, bigger is not always better either (when it comes to intakes), when using large diameter pipes, like enjen ( i think thats the name) you cause the bottle neck effect, which can be worse at the throttle body, killing your volocity completely, same old song and dance!....my 2 cents, im alldone. ;)

:eek: Dang.... I'se getting me a AEM CAI with the Decal !

Then I'll be pushing 200hp :ricer:
