    A short ram by definition doesn't go in the fenderwell.

    I've never heard of a cold air having problems in the rain (there are fender liners) but I have personally seen poorly fitting short rams sit close enough to the crack between the hood and fender that they've ingested water and stuttered. No long term effects though.

    Yes I have A SF intake and I took it through a auto wash once I got out of it my car was running like **** stuttering and didnt want to go anywhere. Shut the car down for an hour let the intake dry started it up died right away. start up again with a little bit of revving it was good to go.


    I'm one of those few that is very skeptical about a CAI I don't feel comfortable with a CAI on my car sure it will be fine in the rain but what happens when you hit a puddle?

Certainly not questioning your facts at all as you obviously have personal experience with it. Just find it an interesting fact. I would always advise that it would be a good idea to have a method of monitoring or logging data regardless just so that I could tell if there were any bad effects of any mod...just in case of a bad install, leak, etc.
    I agree, having an accessport to datalog would be a great idea.

    My experience with the k&n typhoon was on an 06. Personally haven't tried it on a g3, but the engine from 2006-2014 is almost identical with small little differences (mostly intake manifold inter cooler and bypass valve). I'm not sure why the 2008 would be more sensitive than an 06, but if you can provide a good source, that would rock.

    Here's a datalog from someone with a 2009 and a k&n typhoon with no tune.

    The water should deflect off the fenderwell liner if there is no damage.

    Now, submerging the car (a la drews) is a different story.

    Well whether it's maybe safe or not without a tune...it wasn't worth the risk to me. I'm already paying 24k on my car, I wasn't about risk it....that's why I had the k&n and took it off and sold it.

    If I get another, it will be Cobb sf with box...with a tune. That much potential risk is not worth the miniscule gains from a intake...just my 2

    On the 08+ it does sit right in the top of the fender well and is a pretty reputable setup, but water from weather has not really been a known issue with these. And if you are in deep enough water to hydrolock an AEM CAI then your car will likely be inoperable anyhow.

    ^yes me too lol. It was just a recommendation if you get a intake you need to tune for it. If you get a AEM intake or cobb intake without AP your still going to need to get a protune. That might be the cheaper route to go but a AP is a nice thing to have.

    Just thought I would throw it out there that there are other options other than the COBB AP. If you choose to go opensource, you can buy a tactrix cable and use your laptop. Then you can purchase an "e-tune" online that will be custom designed for you. We have a vendor on here called "WTF Tuning" that offers this service. Very reputable and well known tuner. If you choose this route, I would contact them before buying hardware and getting their thoughts on what you should get.

    Cobb AP vs OpenECU (Tactrix/Romraider/ECUFlash)

    (By the way, the author of that thread is the tuner at WTF Tuning)

    FYI--K&N Typhoon 2009 WRX - Subaru WRX Forum
    From what I understand, the 08+ 3rd gen models are in fact different. They use legacy style intakes which were apparently a bit more restrictive, which is why when you add an aftermarket intake at Stage 2 levels, you actually do see gains. Where as when you threw an intake on GD models before and around Stage 2 mods, they really didn't add anything in the way of power.

    That being said, I also ran SPT and Cobb short rams on my first two STIs which were GD models, and had no issues with either of them.

    Secondly, have you ever put a k&n typhoon on, and then had your vehicle checked on a dyno? I have. And it was fine on my vehicle.

    What was your research? Was it factual? I had a K&N typhoon for 85,000 miles. 35,000 of it was untuned.
    Hold up, what's wrong with Eric at TP? I'm working on a stage 2 tune with him, 2 Months after I bought it, very kind and quick to respond.
    Can u elaborate on what unsafe measures he takes?
    I know nothing of tuning and I don't know what would look unsafe.
    I went with him because I was too afraid of using a tactrix cable and this is the first negative thing I've heard.
