K&N Push-In, Screw-In, & Covered Crankcase Vent Filters & Valve Cover Adapters
Tower Base Covered Crankcase Vent Filter with Multi-Hose Vents
High Performance Racing Style - Designed for big bore and full race VW and other like-size engines needing maximum crankcase breathing filtration. Tower design saves blow-by oil while relieving crankcase pressure. High capacity filter element stops dirt from reaching oil supply when decelerating. When installing, bottom fitting should connect to engine's lowest pressure point (such as a rocker cover). Top side fitting should connect to engine's highest pressure point (such as the crankcase).
CAST ALUMINUM TOWER has a universal mount, internal oil baffles and three 3/8" NPT outlets for braided hose fittings.
STEEL TOWER has a chrome finish and no inner baffles. Features an adjustable steel mounting bracket and three 1/2" vent tubes for use with rubber slip-on hose.
