V/C Breather Filter w/o Shield

The V/C Breather Filter without Shield is a critical engine ventilation component designed for high-performance racing and tactical vehicle applications where crankcase pressure management is essential. Built by ALLSTAR PERFORMANCE, this unshielded breather wrap serves as a pre-filter assembly for 3-inch diameter crankcase breather systems, preventing contaminants from entering the engine while allowing necessary airflow. Whether deployed in law enforcement pursuit vehicles, military transport, or competition platforms, this filter maintains engine integrity under demanding operational conditions.

Constructed from durable polyester material in classic black finish, the V/C Breather Filter measures 3.7 x 1.6 x 4.1 inches and weighs just 0.02 lbs, making it an ultralight addition to any engine bay. The unshielded design allows maximum air circulation while the polyester wrap traps oil mist, moisture, and particulate matter that would otherwise compromise engine longevity. This pre-filter configuration is particularly effective in off-road, tactical, and high-vibration environments where stock breathers fail—the absence of a shield permits rapid pressure equalization without sacrificing filtration efficiency, a critical advantage when engines experience rapid elevation changes or aggressive acceleration cycles.

Fleet operators, military vehicle maintenance teams, and performance enthusiasts rely on this filter to extend engine service life and reduce oil vapor emissions in confined crew compartments. The 2.5-inch height and compatible 3-inch diameter mounting make installation straightforward on most round crankcase breather systems without requiring specialty adapters. For vehicles operating in dusty, sandy, or contaminated environments—common in tactical deployments and off-road operations—replacing or upgrading to the V/C Breather Filter without Shield delivers measurable protection against premature ring and bearing wear while maintaining factory-correct breather function.
