ok i have been reading the threads and aem seems good and everyone seems happy with it. I want a v2 but i cant find one for the i4 so i guess its down to short ram or cold air i really dont know which i should do, if anyone has a similar model to my car and have done this or any other intake, reviews would be great thanks guys

 

I have the same car and decided to go with the AEM shorty with their new filter. Why? I'm too old and fat to crawl under and disassemble the front to clean the filter on a CAI!!

 

well im not old but im kinda fat so..... we will see i need to weigh some more pros & cons

 

lmao

 

what do you think lightshow, you seem to be one of if not the most knowledgeable

 

i just posted something about intakes ill find it

 

here ya go

"cold air works on the sole principle of colder air and more flow, which is denser, so more oxygen is sucked in which the computer realizes......sending more fuel into the combustion chamber. a short ram works on the principle of more flow and sound, and when crusing....the temp under hood is not much more than ambient. either model....if they use a metal tube that is not wrapped, will get extremely hot after a while and neither will suck in cold air anymore because the tube will act like a heater. the aem v2 is a cold air intake that factors sound into the equation and the tube is insulated....its my favorite cold air, but i like short rams the best. if every mod you do to the car (intake header exhaust etc.) uses sound as the primary motive. your hp is going to be stirring
"


sound is what you want to use....and im not talking only about more sound or loud sound, im talking about the right sound....at the right time. in your intake you want just the perfect biggest possible sound wave to go into your combustion chamber just as the intake valve closes, pressurizing it. with an exhaust....you dont want two exhaust pulses to arrive at the collector at the same time. its like when your on the freeway and that ****ty**** in front of you has to box in the person who has to merge and everyone has to slow down to 35. if he would have just hung back a few feet, everybody could have cruised at 65. i like short ram intakes the best, but it has to be tuned. when you intake starts to get loud, ie resonates, thats the area where its optimally tuned to send those rarefaction waves back into the cylinder. when the intake gets quiet, those are the areas where it isnt. now with just a regular 3 inch tube shorty intake and your stock intake manifold, you cant make it resonate everywhere....but when you change the length of the tube, you get to choose where those points are. where do i have mine set? 1500-2200, 3200-3900, and 4600-redline. but now make no mistake, there IS a intake and intake manifold combination that will make the sound resonate everywhere. and....the lower the rpm/lower the intake note, the longer the wave is.

 

Super informitive lightshow thanks! Now I have to ask though.... (I bet you saw this one coming...) how did you tune yours and how do you know it's correct?

 

Haha good call sir nasty, i totally agree, and o yea i cant seem to find a v2 for my car the 4cyl 04 model, i can only find the one for the v6 is there anyway that wouldnt be a problem for me to use that one?

 

i tuned it by changing the length. i shortened mine from how it came originally. probably about 6-8 inches. i can get you the details on the length if you want. how do i know its correct? its not........... i know that for a fact. and i wish i could get it to resonate in the 2-3000 range but it doesnt. my knowledge on intake sound really is limited i only know a little bit about a little bit. but what i have been talking about, you can find that on a couple high performance cars out there right now. the focus svt uses a two stage intake system where at a certain point an electronic system changes the intake runner length to get the sound to resonate at a different set of rpms......now the system on the bmw 745 is really what im talking about........ infinately variable intake runner system .....continuously. the intake sound always resonates just perfectly no matter what the rpm is. now these two systems are electronic. there is a way to mechanically set the intake up so that most of the powerband is tuned correctly. sometimes dual throttle bodies helps cause the sound has a shorter distance to travel to that first cylinder as opposed to the back one.
