I took out the cold air box from my NISMO CAI a week ago and was looking at the hole against the fender that is normally used by other CAI systems to allow cooler air to get to the filter, and I thought I might be able to use it. Almost every car I have owned and bought a CAI for has a hole similar to that and the piping actually goes through it into the wheel well, and thats where the filter goes. So looking at the hole I was considering getting some universal piping and a few couplers, and running the filter out above the tire in the wheels well. Has anyone tried this? I know it made a significant difference on my SE-R SpecV and my friends maxima does the same. I just was curious what everyone knows or if anyone has actually tried it. I have considered switching to a new CAI system with a better box but I dont really feel like spending the money when the one I have now is good. Anyway, Im gonna go to autozone, etc and see if I cant find a pipe that will couple to my NISMO CAI and then fit a filter right outside the fender. I had the ram air mod but I think if I could get the filter completely outside the engine bay it would be even better.
