Hey guys i'm in the market for a new intake system but i'm a bit worried about hydrolocking with a cold air intake. I thought it would be helpful to start a thread that could hopefully serve as a compilation of pictures/diagrams of all the different aftermarket intake systems available for the 3G TL/TL type-s.

I'll start with the stock ice box intake system:

diagram originally posted by Bitium
It appears that cold air is collected into a tube at the lower grille (much like a true CAI) and funneled into a secondary tube higher up behind the passenger headlamp.
This setup would be great since it collects cool air from the ground, but the path of the air contains too many bends thus causing restriction.

I'm asking for those who have aftermarket CAIs to please post pictures of the location of the filter cone. If no pictures are available, please take the diagram from above and circle where the collecting cone is located. Any information will be helpful, thanks!

In addition to a visual representation please be sure to include:
Specific Intake: i.e. AEM v2 CAI, AEM v1 CAI, Injen CAI, etc.
Written Detail of Location: i.e. directly behind where the foglight would be on an '07+ model, 3 inches above the grille, etc. Please be as specific as possible!

Hopefully we can get all the CAIs, SRIs, and custom intake mods on here for reference.

 

Here is a custom DIY CAI by JDM5lughatch:


Type: Custom DIY ICEBOX mod
Location: Appears to be directly behind where foglights would go on '07+ models. Need to ask OP to confirm.

I hope we can get real life pictures of the actual cone with the bumper removed on this thread, but i guess having the same diagram recycled and edited with new red circles isn't so bad either. =\

 

Here is a custom heatshield for some SRI made by blue rocket:


and another heat shield that doesn't seem quite as effective:

Appears to be a K&N short ram intake located in the engine bay in the place of the stock air box.

Not trying to get off topic, but blue rocket's heat shield project is an interesting option:

First helpful pic i've found. by Inaccurate:

type: AEM CAI v1?
location: not sure, but pretty low.

AEM v2 Position

According to ib18c1, the AEM v2 "pushes against the fog light and the lower plastic piece. It sits aproximately 1"-2" lower than the v1."

So to give an idea of where the cone sits, it would be somewhere in this area indicated by the red circle:


The v1 should be about 1-2" higher up.

 

To make it simple, all you need is for the air intake to be somewhere outside of the engine bay. It does not have to be in direct airflow, in fact I recommend indirect flow. It can be on the ground or behind the grill, it won't matter power wise as long as it's out of the engine bay.

I recommend putting the filter in the engine bay where it's somewhat protected from the elements.

All I would do is remove the stock intake tract at the silencer and call it a day. It's no restriction at all from that point and it pulls air from outside of the bay.

The stock intake system draws air from down low but once under the hood in the highest spot in the diagram it's got a break in the piping. This is where it goes from blue to orange. At this point some of the cold air mixes with engine bay air. Or put another way, it has a duct from down low outside that blows cool air on the intake plumbing. I'm pretty sure this break is to let any water and excess dirt out before going to the filter.

Hydrolock is very hard to do. Raindrops won't come close, you would have to nearly submerge the filter in water. If you live in an area with puddles, mount the intake up higher. There is no disadvantage to this.

 

first of all, i personally recommend the injen cai.

but mr. ihatecars, a question.. i have that injen cai and i'm jersey or connecticut, so the weather varies. but when i get a car wash that does, let's say an undercarriage wash, with the car running as it is being pushed through obviously, is this a bad thing?
sorry for the run on sentence but what do you think you seem to know a bit

 

@ I Hate Cars: so you recommend the same setup shown in post #2?
