Sorry if I'm hijacking the thread but what's the filtration like on these uprated panel filter, are they just as good as a oem paper filter when it comes to filtering the the air? What would be the condition of the piston rings and cylinder bore engine in general be like after using a uprated panel filter for a number of years? Or Just the same as a engine thats been breathing through a oem one?
Just curious
If your buying from a reputable supplier ie K&N, Pipercross, ITG etc, they all pride themselves on offering superior filtration to the OEM paper filter.
People have used panel filters for 300+ thousand miles in America with no problems
