If you’ve seen what they’ve seen in the bottom of their catch cans, you won’t want that draining back into your oil either. Most AOS systems also drain the blow-by back into the oil pan, while Mishimoto catch cans trap the blow-by and keep it out of the engine permanently. This means that all of the blow-by can condense in the can, including low-octane oil vapors and contaminated fuel vapors. Mishimoto catch cans are different from most air-oil-separator (AOS) systems on a few levels. Like every Mishimoto oil catch can, this baffled catch can kit comes with the Mishimoto Lifetime Warranty! The kit also includes a specially designed, hard-line drain system, complete with a threaded drain plug for simplified servicing and long-lasting protection for your Supra. The Mishimoto Toyota Supra Catch Can Kit includes two pre-molded, direct-fit hoses which require no modification to tie into the Supra’s CCV system. This can mounts in line with the B58’s CCV system and defends the intercooler, intake system, and VANOS system from carbon build-up and helps maintain proper octane levels to reduce potential detonation. The compact catch can is constructed from 6061 aluminum and sealed with Viton O-rings to stand up to anything the Supra can throw at it. Mishimoto's catch can kit utilizes the proven engineering from the patent-pending Mishimoto 2-Port Compact Baffled Oil Catch Can complete with its 50-micron bronze filter and internal baffle to better separate the oil and fuel from crankcase vapors. However, the inevitable side effect of blow-by still found its way to this Supra, which will lead to carbon build-up on the intake valves, eventually slowing this Supra down. The tag-team between Toyota and BMW resulted in a sleek new look for the A90 Supra, teeming with power, technology, and efficiency. Summit Racing Equipment carries catch cans from trusted brands like Moroso, Mishimoto, Canton Racing, Ford Performance, JLT Performance, and many more.The Supra is back! This means that now is the perfect time to add a layer of protection to your B58 with the Mishimoto 2020+ Toyota Supra Baffled Oil Catch Can. These devices are easy insurance for your high performance engine, and some builders use both a catch can and a breather tank. Importantly, breather tanks may not meet local emissions standards. They capture some blow-by with a catch can and air filter, and they may have an oil return. In forced induction and racing applications, the build-up of crankcase pressure can be much greater, so a breather tank is designed to vent that excess pressure into the atmosphere.

Some have a reservoir that needs to be drained regularly, while others are plumbed to return the oil to the crankcase. An oil catch can (sometimes called an air/oil separator) is installed between the PCV valve and the intake, where it removes contaminants and allows only clean air to return to the intake manifold. Normally, the PCV (positive crankcase ventilation) valve uses intake vacuum to relieve the pressure inside your crankcase, but that can result in oil mist and other blow-by contaminants building up on the valve and pistons, especially in direct-injection engines.

Oil catch cans and breather tanks look similar and do similar jobs, but they serve different purposes.
