Question for guys with CAI's - Toyota Nation Forum : Toyota Car and Truck Forums

something i'm concerned about while i'm making my CAI is the way that the engine shakes on startup and stuff. do u guys have a flex joint that will allow the CAI to move a little bit, or is the whole CAI sytem just connected at the throttlebody and not touching anything else along the whole system so it can move around freely? that wouldn't sound right though, how could the whole thing be supported just at that one point. should i make a bracket supporting the system further down that uses a spring or something so it is able to move with the engine?

Mine is so tight that it didn't support it with anything. However, the rubber 90 degree elbow obviously does give it some support...but it flipped off once when I was driving through some rough terrain.

Yea, mines pretty tight too...

Try securing it to a part of the engine itself, that way it'll move with the motor.

the engine doesnt actually have that much rotation under torque, so i decided to support mine a bit more by using one of the body mounts for the bumper to attach the pipe to. now its totally secure.

even if the engine did shake that much, its going to rotate laterally, meaning it would twist with the intake piping. remember the stock airbox? that was totally flush and secured within the engine bay.

True enough.

but between the TB and AFM there is a flex joint (convaluted) on the piping. (at least on my Gen 2)

but it should be okay if i put a mount lower down the piping toward the filter (in the bumper) that will still enable the piping to move a bit should it need to?

Does anyone have a pic of their 2nd Gen CAI?? Preferably where the filter is located. I can't find anywhere to put the filter behind the bumper so I just put on a 90 degree bend and put 2 layers of screening over it for now. and also, kinda off the subject, can someone tell me how an air bypass valve works? and how much they cost?

i'm putting my filter where the old resonator was. have a look under the car in the wheel well on the left hand side and there is a plastic shield, unscrew the forward bolts on that then pull it back, and there is a big white plastic bottle looking thing which i beleive is the resonator. once that is out (there's one or two screws) there is heaps of space to put a filter. my only concern is that there is not a lot of air getting into that area so i might cut the metal in front away to get more airflow in there. i'm almost finished my CAI, i'm just getting a company to weld some stuff for me, at a very expensive price, then i'll do up a tutorial on it.

in relation to the bypass valves i'm not sure how they work, but the AEM ones are roughly US$50.

do u have a web site or ne pics that show how u did it? I''m just tryin to get a feel for how other guys are doin theres.

AEM’s patented air bypass valve virtually eliminates the chance of hydro-lock in the unlikely event the filter of your AEM Cold Air induction system becomes submerged in water. The valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in.The AEM Air bypass valve is for use only on AEM Cold Air induction systems, and is not for use on forced induction vehicles.
