S&S CYCLE Gear Breather - Standard 33-4246

Stock breather systems restrict crankcase evacuation, leading to pressure buildup that compromises seal integrity and reduces engine reliability. The S&S CYCLE Gear Breather eliminates this bottleneck with a high-flow design engineered specifically for performance applications. Whether you're running a naturally aspirated build or preparing for forced induction, this breather ensures consistent scavenging under demanding conditions.

The all-steel construction and welded-in-screen provide durability without sacrificing flow characteristics. The elongated breather pocket scavenge hole increases suction efficiency, pulling vapors and blow-by gases faster than stock geometry allows. This translates to cleaner combustion, extended oil life, and improved ring seal performance—critical factors for any engine pushed beyond stock parameters.
