The Mishimoto Baffled Oil Catch Can Kit is designed and engineered for your 86 to eliminate harmful blow-by vapors from re-entering your engine. The FA20 in the 86 utilizes a slightly different type of direct injection system that also uses port injectors to help reduce carbon buildup. Even though carbon buildup isn’t as severe as most direct-injected engines, there is still enough that you will need this catch can kit to help your boxer engine run its best.
Mishimoto logged thousands of test miles on a Subaru BRZ to determine what can setup would work the best. Their engineers found that with most vehicles, placing the catch can in the vacuum-assisted PCV system of the vehicle will yield the most amount of oil accumulation during normal and aggressive driving, while a catch can placed on the crankcase vent system on the front of the engine will yield nearly no accumulation on stock or modified vehicles. Having only one catch can tied into the PCV system on the back of the engine will, by far, work the best for the vast majority of 86 vehicles on the road. Mishimoto engineers found that a second catch can on the crankcase vent side only benefits vehicles with forced induction.
This catch can kit uses the Mishimoto 2-Port Compact Baffled Oil Catch Can with a bronze filter and internal baffle to better separate the oil from the crankcase vapors. It also includes one direct-fit mounting bracket that is extremely easy to install and fits right-hand drive as well! The 86 catch can kit comes with two direct-fit, pre-molded hoses for ease of installation. The hoses are designed to fit right onto the 10mm PCV valve and into the 12mm port on the intake manifold. Two CNC-machined aluminum, ½” barb fittings connect the hoses to the can.
Mishimoto catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, the Mishimoto 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 the Mishimoto catch can traps the blow-by and keeps 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.
As like all Mishimoto parts, this comes with their Lifetime Warranty!
