Mishimoto Direct Fit Baffled Oil Catch Can for 2018+ Audi S4/S5

Enhance the protection of your 3.0T TFSI engine in the 2018+ Audi S4 or S5 with the Mishimoto Direct Fit Baffled Oil Catch Can. This catch can is designed to address the challenges posed by blow-by gases, a common issue in direct injection engines.

The factory air-oil separator (AOS) system filters some oil and fuel vapors, but harmful contaminants can still reach the intake valves. The Mishimoto catch can installs inline with the PCV system, immediately following the factory separator, providing essential protection for your intake components.

Key features include:

• Patent pending 2-port Compact Baffled Oil Catch Can
• 50-micron bronze filter for effective separation of oil from crankcase vapors
• Internal baffle to enhance oil separation
• Direct fit hoses for straightforward installation
• Two One-Way Performance Check Valves to prevent pressurization
• Petcock drain kit for easy servicing and draining of captured blow-by

Unlike traditional AOS systems that may drain blow-by back into the oil pan, the Mishimoto catch can permanently traps contaminants, preventing them from re-entering the engine. This design ensures that low-octane oil vapors and contaminated fuel vapors are condensed and contained.

This product is compatible with the following models:

• 2019-2021 Audi S4 Premium
• 2018-2021 Audi S4 Premium Plus
• 2018-2021 Audi S4 Prestige
• 2019-2021 Audi S5 Premium

The Mishimoto Direct Fit Catch Can Kit comes with a Lifetime Warranty, ensuring a worry-free installation and long-term performance.
