Twin Air 2 stage air filters are the original dual stage air filters and will fit the 1999-2011 Suzuki RM250, 2000-2010 DRZ400S's, DRZ400SM's, DRZ400E's, and Kawasaki KLX400's from 2003-2004.  The Twin Air #153156 filters fit the original air box and is a 2 stage design which allows maximum airflow while keeping out the dirt.  The first stage traps larger particles and keeps the second stage from getting clogged.  The second stage filters out smaller particles while allowing maximum airflow.  The fused layers of open pore foam and fine inner layer trap even the smallest particles without restricting valuable airflow.  These filters are an almost mandatory addition when purchasing the DRZ400 or KLX carburetor kits.
