I just thought i'd take a look at my air filter,to see how its holding up to our fine climate. Good job too! The Hydroshield's got a hole in it - i figure it's rubbing against something and it was a bit mucky,so i took it off and gave it a good wash. If it's supposed to stop water getting into the filter,why does water flow straight through it then?? The filter itself looks pretty grubby on the outside,although not too bad on the inside,so i guess it has a bit of life left in it? Is it possible to clean these filters? Its the one Forge supplied with the kit. If not,any recommendations for a replacement?
