Granatelli -12AN Screw-In Billet Valve Cover Breather Baffle Kit – 280112
```Add a professional -12AN crankcase ventilation connection to your valve covers without welding with the Granatelli Motor Sports 280112 Screw-In Valve Cover Breather Baffle Kit. Designed for custom street, race and high-horsepower engine builds, this kit provides a clean and secure way to add a breather, catch-can hose, or additional crankcase vent wherever you need it.
The precision-machined -12AN male connection works with compatible -12AN screw-on breathers, hose ends and catch-can plumbing, while the integrated internal baffle helps reduce unwanted oil from being pushed out through the breather system.

Great for Custom Builds: If your valve covers do not have a breather provision—or the existing location does not work with your catch-can or engine-bay layout—the Granatelli 280112 gives you the freedom to add a -12AN connection in a more convenient location.
Integrated Oil-Control Baffle
```Venting crankcase pressure is important, but allowing excessive oil to travel through the breather system can create a mess and contaminate surrounding components. The integrated internal baffle is designed to help separate oil from crankcase vapor before it reaches the breather or catch-can line, helping keep the engine bay cleaner while maintaining effective ventilation.
```Perfect for Performance Crankcase Ventilation
```High-RPM, high-compression and forced-induction engines can generate significantly more crankcase pressure and blow-by than a stock engine. Adding additional breather capacity or connecting the valve covers to a properly designed catch-can system can help manage that pressure in demanding applications. The Granatelli -12AN baffle kit gives builders a clean, compact connection point for custom ventilation systems.
```Ideal For
```What's Included
```- -12AN threaded baffle assembly
- Lock nut for secure installation
- Sealing washer
- O-ring for additional sealing and oil control
Installation Notice: Installation requires drilling the valve cover for the screw-in baffle assembly. The required valve-cover opening is 1.625 inches. Carefully verify the required hole size and installation location before drilling.
```Make sure there is adequate clearance inside the valve cover for the internal baffle and outside the cover for the -12AN fitting, hose, breather or catch-can connection. This is a universal/custom installation and fitment should be confirmed before modifying the valve cover.
