Kia came out of nowhere to stake their claim in the luxury sedan market segment. With the intuitive automatic transmission coupled to the 3.3L twin-turbocharged V6, it’s no wonder the likes of standard benchmarks are worried. The real question is, how long will that last. Direct injection combined with the high-compression of turbocharging means a hotbed for carbon buildup. Luckily, Mishimoto is here to keep your Stinger running to its full potential with the 2018, 2019, 2020, 2021 Kia Stinger GT 3.3L Direct-Fit Catch Can Kit.

The 2018+ Kia Stinger GT 3.3L catch can kit is mounted with a robust, application-specific bracket, the patent pending compact 2-port catch can is installed in line with the factory PCV system in order to separate fuel vapors and oil droplets from the relieving crankcase pressure. As an extra layer of defense, the catch can also includes a 50-micron bronze filter designed for capturing any rogue blow-by particles.

Installation is a breeze with our pre-molded hoses, keeping the time you spend under the hood to less than 30 minutes. Like all Mishimoto products, the Mishimoto 2018+ Kia Stinger GT 3.3L Direct-Fit Catch Can Kit is covered under the Mishimoto Lifetime Warranty to protect your investment on more than one level.

Mishimoto catch cans are different from most air-oil-separator (AOS) systems on a few levels. First, the 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 Mishimoto 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 catch cans, you won’t want that draining back into your oil either.

After installation, Mishimoto recommends checking the contents of the baffled catch cans every 1,000 miles until a baseline is established. Oil blow-by accumulation will vary with ambient temperatures and driving conditions. It is important that the contents of the can do not rise above the internal baffle.
