If an intake is the only mod you are doing to the engine, you probably will not see 10 HP. If you add an exhaust to the car, you will be more likely to get better numbers with all the parts working together. AND THAT is just it, all the mods you do to an engine will work better TOGETHER rather than by themselves.

Exactly I hope they are not expecting stellar performance on just a intake upgrade. As for me I would rather be safe then sorry that is why I put an AEM bypass on my Injen CAI. just click on my website button to see. I would rather not take a chance as to how much water I am going to come up against.

In regards to getting water in the engine, would I still have that possiblity with the Short Ram Ractive? I've always been a little worried about that? If there is the possiblity, would a heat shield help, from not allowing that much water get in?

And your $0.02 is absolutely correct. Somewhere some marketing person at AEM is sitting in a nice big office collecting a fat check because of the raise they got from their excellent marketing job on the AEM bypass valve. If you guys won't take anyone's word for the extremely unlikely event of either intake sucking up enough
water to cause hydro lock in a cylinder, think about this. How many people do you know, or have direct knowledge of, that have damaged an engine because of water intake? How did we ever get along before AEM's invention of the bypass valve? How do those lucky few early buyers of the bypass valve feel about their defective bypass valves dropping springs and other parts into their cylinders?
Think about what needs to happen to suck up enough water to damage your engine. First, you need a considerable amount of vacuum, after all, water doesn't usually have a habit of defying gravity and jumping off the ground and into your engine, now does it? Vacuum increases with engine RPM, so you need higher engine RPM to generate enough vacuum to do the water defying gravity trick right? Second, it would take a larger volume of water than the volume of one combustion chamber at TDC to do damage. Your intake is connected to all four of your cylinders, so it's not likely that any water ingested is going to pick a single cylinder to pick on right? Third, your engine gets hot when it's running, heat is a nasty byproduct of controlled gasoline explosions after all. The closer you get to the cylinders, the hotter it is. So the water needs to escape evaporation and stay in liquid form to damage right? Liquid can't be compressed after all, but gasses can. Fourth, the intake has several barriers to water making it into the intake tube. The filter, gravity, various other parts being in the way, etc. So to sum up, how many of you have a habit of redlining your engines in puddles as deep as your bumpers? Raise your hands.
While I'm at it, neither intake is going to make more than 2 to 3 peak wheel HP by itself. Show me a dyno to prove otherwise. Check out Racing Beats site for more info.

Not to mention the only way you are going to get water in there is to either be driving though some seriously deep water....or trying to wash your car with a 2 1/2 inch fire hose while the engine is running.

sorry...but I had to put in my .02

Thanks, sorry that post was so long, but it's time for people to think about some of the parts they're buying.

i installed just the AEM short ram intake, and so far no problems, ive driven my car through a rain storm, and taken my car through a car wash (the big test) and i haven't had any problems with it, the nice thing about the AEM short ram is that it sits right behind the radiator fans so cool are is being blown onto it

After air passes through the radiator it isn't very cool anymore.

Damn that was good. Funny too.

Yeah, it looks familiar. I have one just like it but blue. I like it mostly because it cleans up the engine compartment. The stock intake takes up too much space, I'll probably move the battery to the trunk also.
