Description
Same as the upgraded version that comes with the Inferno MP9, MP777 WC and the ST-RR. Much better air flow and protection than the old version. The foam also does not react to various cleaners like the old foam. The high-density foam captures the smallest particles to keep your engine in top condition, yet it allows plenty of airflow so the engine can produce maximum power. The angular cut of the foam pre-filter creates more surface area, which means the engine will breathe well even when other filters begin to compromise performance.
