DuraBlue 1126 Air Filter; Power Honda TRX400EX 1999-2009 & TRX450R 2004-2005
DuraBlue's PowerFilters offer unique, proprietary design which increases air flow and air velocity. The result is increased air flow to the engine and, coupled with jetting changes, surges in horsepower. Stock filters gather dirt particles only on one layer, clogging quickly and starving the engine for air.
