Only problem with the ITG/JHP filters is the space that is taken up in what is designed as a pressured airbox. I have used the in tube PiperX ones in the past But in this case he cant use them.
What kind of time scale untill things become worn? Surely not unless you live in the desert running without a filter wont hugley add premature wear to valve seats??
I know of some who have used high denier tights as air filters!!
Big plus point if the JHP type filters are if you end up upside down and tankless in the gravel there is less chance of kitty litter ending up down the inlets.
