Mishimoto 2018+ Audi B9 S4/S5 Baffled Oil Catch Can- PCV Side
Install the Mishimoto Direct-Fit Baffled Oil Catch Can on your 2018+ Audi S4 or S5 3.0T TFSI to shield intake valves from oil vapors and blow-by contaminants that bypass the factory AOS. This PCV-side kit mounts inline after the stock separator for immediate protection using a compact baffled design with bronze filter. Trap blow-by permanently with no drain-back to keep your engine clean longer.
Key Features
- Patent-Pending 2-Port Compact Baffled Design: Internal baffles and 50-micron bronze filter separate oil from crankcase vapors more effectively than stock systems
- Direct-Fit Hoses and Brackets: Billet aluminum brackets ensure plug-and-play installation with no modifications on 2018+ B9 S4/S5
- Mishimoto One-Way Check Valves (x2): Prevent pressurization in the catch can for consistent performance under boost
- Petcock Drain Kit: Quick-drain valve simplifies servicing without disassembly or tools
- Billet Aluminum Construction: Black anodized finish resists corrosion with solid 6061 aluminum body
Product Notes
- Non-heated design condenses all blow-by vapors including fuel and low-octane oil for maximum capture
- Catch can traps contaminants permanently unlike AOS systems that return fluids to the oil pan
- Kit includes everything needed: catch can, hoses, valves, drain, zip ties, and fittings
Installation Notes
- Professional installation recommended.
- Direct bolt-on fit takes 30-60 minutes with basic hand tools. no cutting or permanent mods
