Actually, a cone filter strapped to the MAFS is better than the factory air box, heat soak included.
As an aside (one thing Greg and I did not mention last year), when we dynoed our cars, we saw a gain just by removing the snorkel from the car, but leaving the air box in...not quite as much as the cold air intkaes from MHP and Kore (Gen 1), but there was a small gain.
