I'm looking into getting a CAI for my 08 TL. I currently have the resonator off but I would like to get a real CAI.

I'm just curious as to what is the actual risk of waterlocking your engine. I live in PA winter is so and so and we get a decent amount of rain. Nothing flood level in the Pittsburgh where I live though.. I heard that water would need to get all the way up to where your air filter is to have any risk of this though so it seems like a non issue for me.

Any thoughts? Also any suggestions what kind to go with for a CAI was thinking K&N for obvious reasons.

 

The TL comes with a CAI from the factory. The only difference with aftermarket ones is the filter type and the fact that it's a metal tube. There's always a risk of water getting sucked up but it's minimal unless you're fording a river in your TL. I prefer Injen and Fujita but a lot of people like AEM.

 

Hmm as I said I removed my resonator I believe this was changed on later models as I said I have an 08.

I have seen videos of CAI install on other TLs and you are right the intake is down in the fender well. On my TL though the intake tube loops all the way back up into the engine bay and comes out right by the battery. It is an absolute nightmare to remove I had to remove my battery to reach the bracket holding the intake tube in.

Now that you make me think about it though that definitely makes me feel alot more comfortable getting one especially since I have never heard of anyone having any sort of issues like that.

 

drive your car into a foot or so of water, submerge the intake filter, hydrolock. drive through an 8inch puddle at speed, suck up water, hydrolock.

if you see rain, flooding....stop go back and find another way.

bottomline, your risk is low if you use commonsense when you see standing water. i've never had as issue.

 

You can always add one of these on top of your filter for an extra level of security.

Good idea that's what I was thinking. I'm a bit paranoid about things like this.

 

I've driven in the rain a few times, my car is about a fist off the floor, and my left splash guard behind the fender is ripped up exposing the intake a bit but I have had no problems. I just avoid driving through flooded areas.

To be safe you can always get a hydroshield like the one listed above.

 

You can always create an icebox. Its far less money than a CAI and it'll give you the same advantage. I have mine setup like the M3's where the tubing comes from the stock air box, bend towards the front bumper, then bends down and sits above the bumper grill. Its much harder to suck up water and I put a small hole in the bend so if it does suck water it will drain out.

Moral of the story watch the puddles

 

As far as a dump valve goes for a CAI where can I get one of these I would definitely rather go that route to feel safe. Dosen't look like something that the manufactures sell checked K&N and Injens website.

 

Do you have your heart set on a CAI?

Have you read all of the threads on their uselessness and spending money on PCD's, J-Pipe, etc. Those will actually give you gains, a CAI is just a noisemaker.
