Mishimoto has developed an oil catch can to make sure you're getting the most out of your performance parts. Over time harmful oil will build up inside the turbocharger, intake manifold, intercooler and piping. A Mishimoto Oil Catch Can will prevent this from happening while its all black finish will add a touch of style to your engine bay. An oil catch can serves other important purposes as well. It will prevent oil from getting into pressurized turbo plumbing, which can lead to couplers coming off under boost. Oil vapors can get into the intake system which will lower combustion temperatures and reduce overall efficiency. A Mishimoto Oil Catch Can will solve all these problems and give you the added security knowing that your performance parts are safe from harmful oil. This oil catch can, as with all our catch cans, comes with the unparalleled Mishimoto Lifetime Warranty you know and trust. 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.
