Granatelli Motor Sports Screw-In Baffle Kit – 280112
Easy, Weld-Free Installation for -12AN Valve Cover Breather Systems
The Granatelli Motor Sports Screw-In Baffle Kit (280112) is the ultimate solution for adding a -12AN breather fitting to valve covers without welding. Designed for valve covers that lack existing breather ports—or when an additional breather location is required—this kit delivers unmatched versatility for both street and race engines.
High-Quality -12AN Breather Upgrade for Custom Engine Builds
Featuring a precision-machined -12AN male receptacle, this baffle kit is compatible with any -12AN screw-on breather, hose end, or catch can fitting. Whether you’re upgrading crankcase ventilation, adding a catch can system, or customizing a high-performance build, this kit integrates seamlessly into aftermarket breather setups.
A key advantage is the kit’s integrated internal baffling system, engineered to prevent oil from exiting the breather. This reduces oil contamination, protects engine components, and keeps your engine bay clean while maintaining optimal crankcase ventilation under high-RPM or boosted conditions.
Simple Drill-In Installation – No Welding Required
Installation requires drilling a 1.625-inch (1 1/16") hole in the valve cover. Everything needed for a secure, leak-free installation is included:
- -12AN threaded baffle assembly
- Lock nut for secure retention
- Sealing washer to prevent leaks
- O-ring for added oil control and sealing
Engineered from high-quality materials, the Granatelli baffle kit is built to withstand high heat, vibration, and demanding performance environments. Its durable construction makes it ideal for high-performance street builds, drag racing engines, turbocharged applications, and LS/LT custom valve cover setups.
Professional-Grade Breather System Upgrade
Perfect for DIY builders and professional shops, this kit provides a cost-effective, weld-free method to upgrade crankcase ventilation. Whether you’re installing a catch can system, improving airflow in boosted engines, or adding breathers to custom valve covers, the Granatelli Motor Sports Screw-In Baffle Kit delivers performance, reliability, and ease of use.
Upgrade your engine’s breather system with confidence and experience the benefits of superior crankcase ventilation, reduced oil blow-by, and improved overall engine performance.
