Air intake position

[Bell9266]

How u doin,looking for a bit of advice. As a lot of cold air intakes are positioned at front vents above wheel arch etc this obv increases chance of water entering engine. Will customising inlet hose and repositioning behind headlamp be any good? or am i better off just getting short ram intake but i know this does nothing in terms of gains as i am trying to gain a little hp. any help will be appreciatd.

u can use the cai and put a bypass valve on the intake so u do not have to worry about sucking up water

I have been led to believe this does not fully disable water entering. Also with the intake positioned at the bottom vent will this not eventually clog up the filter if rain and dirt were being brushed onto it. Its just as i from scotland and this is a pretty wet area lol do u not think behind the headlamp would be any good

usually there is nearly no difference in gains between a cold air or short ram. If you are worried about water, just get a short ram.

if your worried about it check out weapon r they make a cai box thats inside the engine bay and they have somethig close to what your looking for. but a sri will work just fine if your worried about running a cai

I realize that I´m resurrecting an old thread but rather than start a new one that overlaps I thought that this would be better. I have been going back and forth over the age old battle between CAI and SRI. It seems that the issue that most folks have with CAI is the possibility of driving through a puddle and getting water in the intake which typically is low to the ground. Has anyone ever tried to take the air from behind, say the diffuser or a hood scoop. Not as low to the ground as the front air dam but high enough so you don´t have to worry about driving through puddles. What do you guys think?

The other option seems to be run the air intake through the front air dam and add on like an AEM air bypass and a TIEN air filter sleeve. Anyone running this setup? If so what is your experience?

Last any recommendations on CAI kits that folks have had good experience with? Thanks.

sorry guys...but CAI's dont do much of anything to a motor for hp...period....ok so your trying to get more air into your motor...whats happening to it when it gets past the CAI??? nothing unless you have another , bigger throttle body and ported /polished head and a better exhaust system to match the front end. All that is happening is your giving your car improper readings to the electronics nothing more.

ok I will give you one for saying that don't do much for hp... however they do a little... and to correct you, CAI's are not to make more volume of air enter your engine they are for allowing colder air to enter your engine... colder air is denser... denser means more air molecules for the same volume which means more fuel can be burnt and more power can be made.

as for the idea of using the hood scoop, it could be a good idea, however the hood scoop is there to keep the exhaust from heating up the firewall too much so there may be some adverse effects of redirecting that air into the intake

Yes. I saw that when I was inspecting the car before buying. At the same time I thought that there might be a possibility of piggybacking an additional scoop , under the hood, just under or to the side of the stock one. Something perhaps that would re direct a portion of that air. The other option is to place a scoop under the hood to collect airflowing through the diffuser. The last spot that I can see would be a scoop that would collect a portion of the air flow from under the upper lip of the lower air dam. I get that it would be robbing the rad of some of its airflow. I wish I could see pics of how others who are running CAI are capturing the air flow. Anyone? Anyone know of kits that have already worked out this problem? Thanks.

Thank you Junkyard for humbling me , that was what I was trying to say, back in the day of American muscle we used to build "cool cans " from coffee cans, aluminum tubing and Ice cubes, to get denser air fuel mixes. today Summit Racing offers them as a pre paid jobber.

Sorry for my newb revelation but thanks to this member for doing this vid and ´posting it in the tech section.

YouTube - How to install an AEM cold air intake on a 7th gen Toyota celica

It helps me visualize this much better. Basically The AEM CAI is just an SRI with longer plumbing. Same filter element, same diameter pipe, plumbed to take air in from a different location. The key difference is that instead of taking the air in from on top of the engine it reaches down to take it from the wheel well. This helped this weekend when I found a shop that did this work. The rep mentioned the AEM kit as one that worked easily with the bypass valve. Who knows.

Is there a third option for better air intake/air intake position? I remember that some member did some mods to his stock box to better the air intake but I can´t remember who it was and I don´t remember a description of what the mods exactly were, for example did it involve adding some plumbing to take air in from a scoop or a ram. Anyone know?
