Breather Element 1/2in w/ Mounting Stud

The Breather Element 1/2in w/ Mounting Stud by ALLSTAR PERFORMANCE is an essential crankcase ventilation component designed for high-performance engine builders and racing enthusiasts. This reusable breather element prevents oil mist and pressure buildup in engine crankcases while maintaining optimal performance during aggressive driving conditions. The push-in design with integrated mounting stud simplifies installation on custom engine builds and retrofit applications where reliable crankcase evacuation is critical to engine longevity.

Engineered with durable rubber and steel construction, this breather element filters contaminants while allowing pressurized gases to escape safely from the engine block. The 1/2-inch hole accommodates standard breather hose routing, and the stud-mounted design ensures secure, vibration-resistant attachment. The black and chrome finish resists corrosion and blends seamlessly into underhood engine bays. Its compact dimensions (4 x 2.15 x 6.95 inches) and lightweight construction (0.21 lbs) make it ideal for applications where space and weight are premium concerns, such as race cars, custom hot rods, and street performance vehicles.

This breather element is ideal for engine builders who demand reliability during high-boost or high-RPM operation. ALLSTAR PERFORMANCE's reusable design reduces ongoing maintenance costs while delivering consistent crankcase pressure management. Installation is straightforward—the push-in configuration and mounting stud require only basic hand tools and minimal fabrication. Whether upgrading an existing engine or building from scratch, this component integrates seamlessly into custom air management systems and is compatible with most 1/2-inch breather line setups found in performance engines and vintage hot rods.
