I've heard that a cold air intake will give you a bigger low end power boost and a short ram intake will give you a more mid to high rpm boost. Is that true?

 

I would imagine so... short ram creats higher velocity... cold air when at high RPM's can keep up with the short rams velocity hints why you maintain the better boost at higher RPMs.... not positive but im pretty sure.

 

Here's the scoop. A CAI will keep your CEL from coming on because it's not sucking up hot engine bay air, but has a better chance of sucking up water if it sits low enough. A RAM will not suck in water, but will suck up hot air and cause the CEL to come on. Hot air = not as dense, cold air = dense. The cooler the air, the more you can fit in the chambers, the closer to stoich the motor will run, the more performance you get out of it. Opposite for hot air.

 

Injen also makes a little hydro cover that you can put over the filter and stop water from being sucked up : )

 

not only that there is also this bypass cuplink that sits right before your tb and if the CAI is submerged it sucks from the filter infront of your tb and not from the one at the end of the CAI that works amazingly. watched a vid on how it works. would rather get that then the hydro cover cause tha proably robs HP

 

I doubt a company like Injen would use it if it robbed power.
