Baffled Oil Catch Can Audi S4/S5 B9 2018+Give the 3. 0T TFSI powering your 2018+ Audi S4 or S5 the extra layer of defense that it needs with the Mishimoto Baffled Oil Catch Can. Volkswagen and Audi were on the front lines of the direct injection revolution, which means they were also one of the first to implement a means to protect against blow by gases. While the factory AOS system does filter out some oil and fuel vapors, the harmful contaminants still make their way to the intake valves.

Give the 3.0T TFSI powering your 2018+ Audi S4 or S5 the extra layer of defense that it needs with the Mishimoto Baffled Oil Catch Can. Volkswagen and Audi were on the front lines of the direct injection revolution, which means they were also one of the first to implement a means to protect against blow-by gases. While the factory AOS system does filter out some oil and fuel vapors, the harmful contaminants still make their way to the intake valves.

The Mishimoto Baffled Oil Catch Can for your 2018+ Audi S4/S5 installs in line with the PCV system right after the factory separator for immediate protection of the intake components. Our catch can features a patent pending 2-Port Compact Baffled Oil Catch Can with a 50-micron bronze filter and an internal baffle to better separate oil from the crankcase vapors. Our kit also includes a set of direct-fit hoses for a simple installation, including two Mishimoto One-Way Performance Check Valves to prevent your catch can from becoming pressurized. In order to simplify servicing, our kit includes a petcock drain kit so draining captured blow-by is a cinch. The Mishimoto 2018+ Audi B9 S4/S5 Baffled Oil Catch Can also includes the Mishimoto Lifetime Warranty for a worry-free installation.

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.

          Loving this blanket and planning to order 2 more in different colors.
          Color: Khaki, Size: Queen(90×90in)
          Love the look and feel of this blanket. Good quality and great prices. I ordered a queen size and is perfect. Really love it. Plan on purchasing a couple more, like this one for 2 other bedrooms, in different colors. Really love this blanket.

          As expected, good quality for price
          Color: Khaki, Size: Throw(50×60in)
          Very soft, color is exactly what I expected. These are thinner than most so don’t expect a big cozy throw blanket. They’re big enough to snuggle up on the couch but it share with anyone (: I did not have an issue with shedding, although I’ve washed them a few times now and am worried they might start to thin on me. Very soft and doesn’t get “matted” when washed and dried.

          So soft and cozy
          Color: Sage Green, Size: Throw(50×60in)
          This blanket is perfectly lightweight and cozy warm. The color turned out just as I was hoping and the material is so soft. My daughter immediately claimed it as her own. It’s a smaller throw - perfect for our couch. Great value blanket.

          Not for me
          Color: Khaki, Size: Throw(50×60in)
          It was soft but so thin. I don't know how it had a such a high review. People be doing too much and not being honest. It's getting ridiculous. If AI is involved that would explain it. Not warm. Not thick. Not big enough... it's a no for me

          Obsessed With This Ultra Soft, Fluffy, Cozy Blanket
          Color: 02 Crystal Pink, Size: Twin (60" x 80"), Color: 02 Crystal Pink, Size: Twin (60" x 80")
          I absolutely love this blanket. I ordered the crystal pink color in the 60x80 size to use as a throw blanket for my new cloud couch in my office, and honestly it ended up being exactly what I was hoping for. The material is incredibly soft, fluffy, and comfortable without feeling thin or cheaply made. I’ve actually been searching for another blanket similar to one I previously owned that eventually got a hole in it, and this one gave me that same cozy feeling immediately. It’s one of those blankets you instantly want to curl up in the second you touch it. One thing I really liked is that the bubble texture actually has dimension and volume to it. A lot of blankets advertised with this kind of design end up looking flat in person, but this one genuinely has that plush “bubble” effect and makes the blanket feel extra cozy and luxurious. The size is also great. It’s large enough to comfortably use on a couch while still being big enough for a twin bed if you wanted to use it that way. For me personally, it’s the perfect oversized throw blanket size. I honestly have nothing negative to say about it. The quality feels great, the stitching looks well done, the color is beautiful, and overall it feels thoughtfully made rather than cheaply mass produced. For around $25, I absolutely think it’s worth it. This has easily become one of my favorite cozy blankets in the house.
