Unlike a standard PCV system that routes crankcase gases back into the intake manifold, an open breather filter vents directly to air, making it the preferred choice on dedicated track cars, drag builds, and any engine running so much blowby that the factory PCV system cannot handle the volume without saturating the intake with oil mist. Performance engines that produce significantly more blowby than stock through increased displacement, high-lift camshafts, or forced induction benefit most from breather filter upgrades that vent excess crankcase pressure without contaminating the intake charge. Proper crankcase ventilation reduces oil consumption, keeps the intake tra...
