K&N Performance: K&N Performance Gold Oil Filter Buick V8 69-71 Keep your engine free from contaminants as small as 10 microns with these Performance Gold K&N oil filters. They use a resin-impregnated filter media to provide maximum filtering along with an inner core to lend extra structural support to the filter which prevents filter collapse. Plus, these K&N oil filters have an anti-drainback valve that eliminates dry starts and prevents oil from draining back into the crankcase during engine shutdown. And they're protected by a heavy-duty outer shell that guards against rock and stone damage and provides over 550 psi hydrostatic burst strength.
