Mishimoto Baffled Oil Catch Can Kit – 2018+ Audi S4/S5

Description

The Mishimoto Direct-Fit Baffled Oil Catch Can Kit, MPN MMBCC-S4-18PBE, is engineered specifically for the 3.0T TFSI engine found in the 2018+ Audi S4 and S5. Rather than a generic add-on, this is a purpose-built catch can that mounts in line with the PCV system immediately after the factory separator, giving the intake valves an extra layer of defense right where blow-by first escapes the crankcase.

Anyone researching car engine parts, engine parts, or the components of an automobile engine knows that direct injection engines are especially vulnerable to oil and fuel vapor contamination on the intake valves, since automobile combustion in these engines bypasses the fuel-washing effect port injection provides. This Mishimoto catch can addresses that gap in the parts of a car’s engine bay by trapping blow-by permanently instead of draining it back into the oil pan like many factory AOS systems do. Inside the patent-pending 2-port Compact Baffled Oil Catch Can, a 50-micron bronze filter and internal baffle work together to separate oil from crankcase vapor, while an internal air diverter turbulates the air longer to improve that separation. Because the can itself is not heated, condensation of low-octane oil vapor and contaminated fuel vapor is more complete, helping maintain proper octane levels and reduce the potential for detonation—an important consideration for anyone focused on protecting car engines and the parts inside them.
