So I was at a car show last year and saw a guy running a custom cold air intake made from PVC pipe and a cheap cone filter. I figured it was just for looks, but he swore it dropped his intake temps by a few degrees. I tried something similar on my Mustang using plumbing supplies from the hardware store, and honestly, it worked better than I expected. The throttle response felt a bit sharper, and it sounded awesome under the hood. Anyone else tried a mod that sounds totally sketchy but actually paid off?
