I currently have an Arlen Ness inverted cone air cleaner fitted, PV tuned. However, after sustaining a minor knee injury, stretching my leg around the cleaner to reach the brake is causing some grief, so to make for an easier riding position I'm going to replace the Ness unit with Performance Machine's slimmer Max HP product c/w K&N filter E-9156. Does anyone know if there's sufficient difference in airflow between the two filters to need another PV tune, or will it be just plug and play?
