I bought an AEM style cold air intake from Ebay that didn't come with any instructions. While looking at the AEM instructions it talks about an air horn that is supposed to be installed between the filter and the pipe i think. My kit didn't come with one of these. It looks like my filter should slide right on to the tube and tighten down with the hose clamp. But my kit has three of the connector hoses, one that connects to the pipe to the throttle body, one that connects the two pipes together, and one more that I don't know what it's for. Do I even need an air horn? Sorry this is so long, I'm new to this.
