I have yet to see any filter on any of my last 3 cars that made any sense to me in terms of the reduced filtering vs power gained. I swapped my us filter for the eu to lose the charcoal element (orig AA filter), but that's all. Most high performance cars these days come with incredibly well engineered intake tracks.
