Mishimoto Baffled Oil Catch Can Kit Black Subaru WRX 2015-2021

The Mishimoto WRX Baffled Oil Catch Can System is designed and engineered to reduce carbon buildup, a common issue with direct fuel injection engines such as the FA20-DIT. This WRX system includes two patent pending Mishimoto Compact Baffled Oil Catch Cans, designed to separate oil particles from the PCV/CCV air that would normally be routed back to your intake. The internal air diverter increases air turbulence and ensures all the oil sinks to the bottom of the can, leaving nothing but clean air to pass through the 50-micron bronze filter to the intake. An internal baffle keeps the collected oil from splashing around under race conditions.

The 100% billet 6061 aluminum cans include two black aluminum fittings and are sealed with Viton™ O-rings. Also included are two direct-fit steel powder-coated brackets, which mount the cans in serviceable locations. This makes maintaining your WRX system a breeze, as the cans are also 100% washable, unlike many other cans that require you to replace your filtration system. To connect the cans to your PCV and CCV systems, the Mishimoto WRX Baffled Oil Catch Can System includes application-specific, pre-molded hoses for an easy install to keep your engine bay looking clean! Whether you are entering your WRX in the local rallycross or lapping at your next track day, trust Mishimoto and our line of WRX parts to keep your WRX cool. This kit, like our entire line of WRX parts, includes the signature Mishimoto Lifetime Warranty.

Our catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, our catch cans are not heated. This means that all of the blow-by is able to condense in the can, including low-octane oil vapors and contaminated fuel vapors. Most AOS systems also drain the blow-by back into the oil pan, while our catch cans trap the blow-by and keep it out of the engine permanently. If you’ve seen what we’ve seen in the bottom of our catch cans, you won’t want that draining back into your oil either.
