actual fact.
My personal feelings on that (no hard data to back it up) is that a lot of the performance filters/intake just have an open cone type filter under the hood, so the engine is sucking hotter air in. I prefer to stay with a stock style paper filter with an actual cold air intake. I still run a system like this on my 99Z28, and when I put the cold/ram air on, I picked up almost a full 1mph in the 1/8 with similar DA
