About the Stillen G3 Intake
 

Hello everyone. Does anyone know how often do I have to change my filter? And am I able to buy them in Australia? Thanks for help.

Not sure about buying in Australia but you dont have to change your filter really ever unless it is damaged, you just have to clean them with KandN's cleaning kit every 20 or 30k miles depending on the driving conditions you face (dirt, dust, etc.)

I read to recharge the filters every 50k mi

driving condition quite good, so I think I will just clean them every 30k then, thanks guys.

U can order those from auto-barn or rapco in australia but they are much more expansive than buying online

Are the stillen intake filters oil based? Can our MAF handle it?

They are K&N filters do they are oiled. So long as you don't over-oil them, the NAF sensors should be fine.
