I would perfer the AEM V2 Intake because you can get at least 8-10 HP guaranteed. But that thing cost like 200 dollars. So you can try anyother brand as long as it is a cold air you would get more of a kick in the car. Also I suggest you get a bypass valve also. This would prevent water from getting into the engine and thus saving you alot of money. Putting in the intake is as easy as peeling a banana. Take off the old one and attach the intake to the intake manifold and tighten that part. for a cold air intake it would be a llittle harder because you have to take off more things. But this is how to install a short ram intake. Like i said before take off the old one install the intake to the manifold then clamp it down. Install the air filter to the end pipe and clam that down and then lastly get a small tube that would fit that small sticking out part from the valve head and connect it to that to the intake. There should be some thing sticking out of the intake. well hope that helps.
