Do you think there is any benefit in adding an upgraded air filter?
A question I've asked myself. After much reflection my answer is probably not. The intake is not restricted, so fitting a "free flow" filter wouldn't do much.
The only question is "how dirty is the filter?" I assume it is a paper element that will get blocked with fine dust over time.
It would be possible to fit a K&N foam cone but it would need to be outside the engine bay to get cold air.
