Oil Catch Cans

Oil catch cans (also called air-oil separators) are a critical component for direct-injection and forced-induction engines. They intercept oil-laden blow-by gases from the PCV system before they reach the intake tract, preventing carbon deposits on intake valves, reducing detonation, and maintaining intercooler efficiency. Whether you're building a daily driver or a dedicated track car, a properly sized catch can helps keep your engine running clean.

Our collection includes a wide range of oil catch cans, from simple inline units to high-capacity baffled and vented designs. Key features to consider when choosing a catch can include:

  • Capacity: Larger cans require less frequent draining—ideal for high-horsepower applications.
  • Mounting: Universal cans with brackets offer flexibility, while vehicle-specific kits provide bolt-on installation.
  • Construction: Look for materials like billet aluminum or steel with durable, chemical-resistant seals.
  • Features: Integrated dipsticks, drain valves, and internal baffling improve usability and effectiveness.

Find the right oil catch can for your setup and fend off carbon buildup before it starts.
