Granatelli Pres-In PCV Valve Cover Breather

Performance Air Filters and Replacement Filters This collection covers filtration for factory air boxes, aftermarket intake systems, custom intake tubing, crankcase ventilation and vehicle HVAC systems. Start with the installation type, then confirm the exact manufacturer part number, filter media, dimensions and application shown on the product page. Similar-looking filters are not automatically interchangeable. Choose the Correct Air Filter Type Direct-fit and drop-in filters: shaped for a specific factory air box or listed intake system. Universal clamp-on filters: selected by flange inside diameter, base and top dimensions, height and available clearance. Cabin and HVAC filters: vehicle-specific filters for air entering the passenger compartment. Breather filters: compact filters for compatible valve-cover, crankcase-vent and catch-can applications. Pre-filters and wraps: outer covers designed for compatible primary filters in dusty, sandy or wet environments. Velocity...

Engine breather filters are vented filtration caps and inline filter assemblies that allow crankcase pressure to vent safely to atmosphere without releasing raw oil vapor, reducing the internal pressure buildup that can push past valve cover seals, rear main seals, and PCV grommets in high-output and modified engines. 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...
