I got on the highway for the first time with the new filter today. WOT, 3rd gear, 4000+ rpms, I hear a "swoosh" kind of sucking sound. This doesn't happen at low speeds. Must have something to do with the front facing intake forcing more air in at speed. I wonder if that translates to more performance though. We'll never know...
