PQY Universal T304 Stainless Steel E-VAC Scavenger Kit — E-VAC fitting set with 10-AN bung & M18 O2 bung for race engines

The PQY Universal T304 Stainless Steel E-VAC Scavenger Kit is a complete, durable vacuum scavenging solution that reduces crankcase pressure and supports higher horsepower in high-performance and race engines.

This kit supplies a corrosion-resistant T304 stainless steel E-VAC fitting set designed for custom installs and motorsport use. Built with race-proven components, the PQY kit combines an integrated 10-AN male E-VAC bung, an angled M18 O2 bung, and an M18 x 1.5 male threaded plug to give tuners and fabricators flexibility when routing vacuum and vent lines. Each component is machined for fit and longevity so you can integrate it into valve covers, intake manifolds, or custom housings.

How does the PQY E-VAC scavenger kit improve engine performance?

The E-VAC scavenger kit reduces crankcase pressure by actively pulling vacuum from the crankcase, which can lower parasitic losses and help ring seal. On dyno-tested race engines this setup has been shown to pull up to 3" of vacuum under load, helping the engine breathe more efficiently during high RPM operation.

• Dyno-proven capability to reach approximately 3" Hg vacuum on race engines
• Removes excess blow-by gases to reduce crankcase pressure
• Improves ring sealing and can reduce oil consumption in race conditions

What parts are included and why are they useful?

The kit contains a Male E-VAC fitting with an integrated male 10-AN bung, an M18 angled O2 bung, and an M18 x 1.5 male threaded plug. Those elements give fabricators multiple routing and sealing options so the kit can be adapted to many custom manifolds, valve covers, and catch-can setups.

• Male E-VAC fitting with integrated 10-AN bung for low-cost connection to AN lines
• M18 angled O2 bung to allow sensor or hose placement in tight areas
• M18 x 1.5 threaded plug to seal unused ports cleanly

Is this kit compatible with my build and how easy is it to install?

The PQY kit is described as universal for custom installations and fits many engine and chassis configurations that accept M18 fittings and AN plumbing. Installation typically requires drilling and tapping the desired mounting surface or adapting to existing ports, so some fabrication or professional installation is often recommended.

• Universal design fits many custom and motorsport setups
• Requires compatible port size or simple fabrication to integrate
• Designed for durable T304 stainless steel construction to withstand harsh environments

What materials and build quality can I expect from PQY?

All parts in this set are machined from T304 stainless steel, chosen for corrosion resistance and strength under heat and vibration. The robust construction helps ensure reliable sealing and long service life in performance applications.

• T304 stainless steel for corrosion and temperature resistance
• Precision machining for consistent thread and sealing surfaces
• Includes mating plug and bungs to prevent leaks and simplify plumbing

Who is this for: The PQY Universal T304 Stainless Steel E-VAC Scavenger Kit is aimed at racers, performance engine builders, and custom fabricators who need a flexible vacuum scavenging solution. If you run high-revving or heavily modified engines and want a durable, install-friendly kit to manage crankcase pressure and integrate AN plumbing or O2-style bungs, this set provides the core hardware for professional installations.
