If its a new filter element, you can have it cleaned a couple of times before replacing. As for the frequency, it depends on how dirty the air is in your area. In my case, cleaning/replacing is done during my 5,000 km intervals unless I feel the car seems to lack power.


do they also apply this computerized tuning to open-loop system?
no, its a manual operation but its possible to have an accurate tuning done with a wide band oxygen sensor. Greenfuel is partnering up with Speedlab for their more advanced tuning capabilities.
