The Super Power Flow replaces the factory airbox with an open cone element that mounts straight onto the stock mass air flow meter. This application ships with the HKS Φ200-80 green filter, a dry three layer media that is cleaned and refitted without any oiling step, unlike the red wet element HKS offers as an alternative. HKS states the kit leaves stock feedback control intact, so no ECU reset is needed under normal circumstances, and reports sharper throttle pickup with smoother midrange response. Because output rises, HKS recommends moving to a higher heat range spark plug, and the element needs regular cleaning to keep flow up.
