Thought I'd share my CAI pipe made from Home Depot PVC pipes...just 3" black pipe, a 60* bend and a 3" - > 2" adapter to fit to the throttle body with a rubber fitting and clamps. Works great, and I think it looks better in my dirty engine bay than an outstanding shiny chrome pipe! Filter is AEM dryflow 3x5"
You can hardly see it but I have a (poorly) fashioned shield to act as a condom around the filter. I made this out of cheap aluminum roofing. It seems to keep some of the heat out but as importantly is effective in blocking water from splashing up. It's attached with brackets made from the same material looped into the clamp.
Total cost including AEM filter was about $60.
