Haha i just got a unifilter droopie prefilter and a ram head prefilter for a trip to birdville im doing in a week..i was talking to unifilter and they said the ram head is mainly for sticks...bugs and a bit of dust.
Where the droopie is the real prefilter.should catch 90% or anything that comes down the snork.im gunna run them both.as i have a apollo pod filter on mine which lets a fair bit of fine dust thru normally.they tell me there will be no loss of airflow with one or the other....even both so i figure run both as i like my engine to breath clean.
