I am thinking of fitting an induction kit from BMC filters on my 93 348. However, I was wondering if anyone has done it and is it worth it. Plus if I do fit it, will I need to have the ecu remapped for higher airflow. All advice would be greatly appreciated. Andy
I haven't done it. Others seem to like the K&N filters. As for remaping the ecu's, not needed, they self adjust. Unless you are cramming air into the engine, via a turbo/supercharger, there is no need to fool with the ecu's.
