Breather Filter w/6an Fitting

The Breather Filter w/6AN Fitting by WEHRS MACHINE is a precision engine breather assembly designed for high-performance vehicles and racing applications where crankcase ventilation demands reliability and flow efficiency. This aluminum breather eliminates vacuum leaks and pressure buildup in sealed engine systems, making it essential for supercharged, turbocharged, or high-RPM naturally aspirated engines that require controlled crankcase evacuation. Built for mechanics, fabricators, and performance enthusiasts, this compact unit integrates seamlessly into custom engine bay layouts where space and cleanliness matter.

Constructed from blue anodized aluminum, the breather filter features a clamp-on round design with a 1/2-inch outer diameter tube connection and 6 AN male adapter fitting, enabling quick integration into AN-plumbed fuel, coolant, or vacuum systems. The anodized finish provides corrosion resistance and durability under engine bay heat and moisture exposure, while the compact 4.85 x 1.75 x 5.05-inch footprint allows flexible mounting in tight fabrication scenarios. The included 6 AN fitting eliminates the need for additional adapters, reducing installation time and potential leak points in the breather circuit.

Performance builders, engine shops, and street rod fabricators benefit most from this breather assembly when constructing custom induction or vacuum systems for LS engines, big-block Chevys, and other modern performance platforms. Installation requires basic hose routing knowledge and standard hand tools; the clamp-on design accommodates 1/2-inch hose without additional fittings. Weighing only 0.1 lbs and designed for both show and street use, this breather filter maintains engine health by preventing oil vapor escape while keeping crankcase pressure balanced—critical for longevity in turbocharged and supercharged builds.
