Clamp On Filter Breather W/Shield 1-3/8In Hole

The Racing Power Co-Packaged Clamp On Filter Breather with Shield for 1-3/8 inch hole applications is a direct-mount crankcase ventilation component designed for engine builders and performance enthusiasts who require reliable blow-by management. This half-shielded breather assembly combines a rubber and steel construction in black and chrome finish, engineered to mount cleanly to tank and reservoir openings without requiring welding or permanent modification.

The 1-3/8 inch hole specification accommodates standard crankcase breather ports found on many small-block and mid-range engine builds. Clamp-on installation ensures quick assembly and disassembly during maintenance cycles. The half-shield configuration provides adequate protection against splash and debris ingestion while maintaining minimal backpressure on the crankcase ventilation system—critical for engines running sustained boost or high RPM regimens where excessive crankcase pressure compromises seal integrity and oil consumption.

This breather suits hot rod builders, engine machine shops, and performance street and track enthusiasts assembling carbureted or fuel-injected mills where factory emissions equipment has been removed. The round design and compact profile (7.9 x 3.25 x 8.85 inches, weighing 0.6 lbs) fit tight engine bays without interfering with header clearance or intake manifold geometry. Chrome and black finishes integrate with both show-quality and functional build aesthetics.

Racing Power Co-Packaged components are engineered for straightforward installation and proven durability in street and strip environments, making this breather a practical choice for builders who prioritize simplicity and reliability over proprietary or custom-fabricated solutions.
