The filter for a SRI sits directly on top of the hole through which the stock resonator tube passes which is right beside the battery. It is pretty far forward, not near the wheel well. Search for pictures to show you exactly where it sits.

The purpose of a cold air box is to give you a large volume of cold air that is right there for quick throttle response. CAIs take longer to draw this air in because it has to come from further away and the tube has more bends. That is generally why SRIs perform better than CAIs down low. The benefit of the cold air box is that this air is also cold, unlike a standard SRI which draws air in from the hot engine bay.

To function properly, the cold air box must be reasonably well sealed and fairly large. More important, however, the inlet source for the cold air box should be at least as large as your intake tube. If you just use the stock resonator hole to feed your cold air box, you will get no better performance than the stock intake because that small hole limits how much air you can draw in.

When I make my box, I plan to enlarge the stock resonator hole, and also to add a second source from the foglight opening. This will ensure that I always have more air in the cold air box than my short ram intake can use.
