Crawford V3 Air Oil Separator: The Performance Standard

Proprietary Dual Chamber Design

The V3 uses Crawford's exclusive dual-chamber technology that outperforms traditional single-chamber separators. Oil droplets pass through two distinct separation stages, capturing more contaminants before they reach your intake system. This translates to cleaner combustion chambers, reduced carbon deposits, and sustained power output over time.

Emissions Compliant Engineering

Unlike many aftermarket solutions, the V3 retains your factory PCV valve configuration. This keeps your vehicle compliant with emissions regulations while delivering superior performance. Daily drivers benefit from this design since it maintains all OEM safety and regulatory functions.

Track-Proven Durability

Built with aerospace-grade aluminum and featuring CNC-machined components, these separators handle extreme conditions without failure. The internal baffle system manages high-G cornering forces while maintaining consistent separation efficiency. Temperature cycling from -20°F to 250°F won't compromise performance or structural integrity.

Installation Specifics

Each kit includes vehicle-specific brackets, pre-formed silicone hoses, and stainless steel clamps. Installation typically requires basic hand tools and takes 2-3 hours. The kit integrates with your existing PCV system without modifications to engine management or requiring custom tuning.

Performance Impact

Independent dyno testing shows V3-equipped engines maintain 95% of their original power output after 50,000 miles, compared to 85% for engines without proper crankcase ventilation. Blow-by contamination drops by 78% versus stock PCV systems, reducing the frequency of intake cleaning services.

Maintenance Schedule

Empty the collection chamber every 3,000-5,000 miles depending on driving conditions. The entire process takes under 10 minutes and requires no special tools. High-performance driving or track use may require more frequent servicing.
