Description
The Mishimoto Baffled Oil Catch Can Kit, part number MMBCC-F80-15CFDG, was engineered specifically for the turbocharged S55 engine found in the F8X-chassis BMW M3 and M4. When BMW brought factory turbos to its compact M cars in 2015, it also brought back an old headache for owners of high-performance car engines: crankcase blow-by. This kit tackles that problem head-on with a purpose-built, application-specific design rather than a generic universal catch can.
Built around the proven engineering of the patent pending Mishimoto 2-Port Compact Baffled Oil Catch Can, this system uses a 50-micron bronze filter and an internal baffle to separate oil from crankcase vapors before they ever reach sensitive components. A CNC-machined lid features large inlet and outlet ports sized to match the inner dimension of the CCV hose, so oil-laden vapor moves efficiently through the can instead of backing up into the engine. Because the can is unheated, blow-by fully condenses inside it—including low-octane oil vapors and contaminated fuel vapors—and stays trapped rather than draining back into the oil pan the way many air-oil-separator systems work. That means the catch can defends the intercooler, intake system, and VANOS system from oil contamination while helping maintain proper octane levels to reduce potential detonation, keeping the parts of a car engine that matter most running cleaner.
Vehicle Applications
This Mishimoto catch can kit is a direct fit for 2015-2018 BMW M3, 2015-2020 BMW M4 Coupe/Convertible, the 2016 BMW M4 GTS Coupe, 2019-2020 BMW M4 CS Coupe, and 2019-2020 BMW M2 Competition—all built on the F80, F82, F83, and F87 chassis codes and powered by the S55 engine. The included hoses and mounting bracket are application-specific, so installation requires no modification to the engine cover on any of these models.

Frequently Asked Questions
Which BMW models does this Mishimoto catch can kit fit?
This kit is a direct fit for the 2015-2018 BMW M3, 2015-2020 BMW M4 Coupe/Convertible, 2016 BMW M4 GTS Coupe, 2019-2020 BMW M4 CS Coupe, and 2019-2020 BMW M2 Competition, all built on the F80, F82, F83, and F87 chassis with the S55 engine.
What is included in the Mishimoto MMBCC-F80-15CFDG kit?
The kit includes one Compact Baffled Oil Catch Can, one application-specific mounting bracket, two direct-fit hoses, two 3/4-inch aluminum barbed fittings, four worm gear clamps, mounting hardware, and the Mishimoto Lifetime Warranty.
Does installing this catch can require modifying the engine cover?
No. The kit’s direct-fit hoses and application-specific bracket allow installation with no modification to the engine cover.
How does the catch can separate oil from crankcase vapor?
It uses a 50-micron bronze filter and an internal baffle to separate oil particles from crankcase vapors, with an internal air diverter that increases air turbulence to improve oil separation.
Why doesn’t this catch can drain oil back into the oil pan like some AOS systems?
Unlike heated air-oil-separator systems that drain blow-by back into the oil pan, this Mishimoto catch can is unheated, allowing blow-by—including low-octane oil vapors and contaminated fuel vapors—to condense and stay trapped in the can rather than returning to the engine.
What color options are available for the mounting bracket?
The aluminum mounting bracket is available in 12 BMW specific color-matching options, such as Frozen Dark Grey Metallic, or in classic black.
