The price has alot to do with quality of the product and also how complete the setup is. Some people think that the Iceman is a ripoff because it is made out of plastic instead of aluminum. PLastic has many advantages over the aluminum in this application. It allows the air to remain cool as it passes by the engine. If you are looking for an intake that will give you torque go with the iceman, if you are looking for top end hp then go with something that has a cone filter (AEM, Volant,...) I personaly have the Iceman. I have removed the stock air box though and am using a cone filter. With this setup I can easily change back to the stock airbox if I desire having more torque. Hope this helps with some of your questions.
