The filter doesnt need to have an open end to have a high flow!


Look at every single 1/8 buggy air filter... They are almost excatley the same. The air is drawn through the side foam to the center of the filter where it is pulled down the carb.....


The motor savers suck ass too... They allow unfiltered dirt to sneek past the foam at the bottom of the cage ( where the neck meets the screen case)

Just buy a mugen 1/8 filter and be done with it already
