Newbie here asking what may be a silly question. What is the significance of the small air cleaner that you are on most boats. In all other performance engines. The air cleaners are one of the first improvements made but u haven't seen many larger free flowing air cleaners in inboards. Just wondering.

air cleaner is a spark arrestor...prevents any ignition from the motor box due to back fire.
