Give the 3.0T TFSI powering your 2018+ Audi S4 or S5 the extra layer of defense that it needs with the Mishimoto Direct Fit 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 gasses. 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 Direct-Fit Baffled Oil Catch Can Kit 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 Direct Fit Catch Can Kit 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.This Part Fits:

Works as described
Color: Black
Love this whisk. I have arthritis and this is light weight enough for me to use. I love the push button, and the stand for it. It’s really easy to clean, and it blends my shakes nicely without leaving the powder behind.

Very Powerful Frother!!
Color: White
I’ve been using a frother daily for my drinks, and this one really impressed me with its power for such a compact size. It blends heavier powders into smooth, clump-free mixtures in seconds.
I’m a big fan of the build—the metal whisk gives it a solid feel, and it comes with a stand to keep it neat on the counter instead of being shoved in a drawer. Cleaning is a breeze, just a quick rinse, and the rechargeable battery lasts much longer than I anticipated between charges.
Just a little tip: start in a taller cup and don’t fill it all the way to the top, as this thing can create a serious vortex if you’re not careful. Overall, it’s been a super handy little tool, and I’m so glad I bought it.

Mixes my protein shake powder
Color: Blue
My husband and I both drink protein shakes daily. We have vortex mixers that work great, but they are plastic and getting old, and really needed to be replaced.
In an effort to reduce microplastics in our lives, I am trying to use less plastic mixing cups. I couldn't find anything small enough (other than regular blenders) with glass and metal parts that would work well for us.
During my search on here, several frothers showed up. This one caught my eye because of the amount of sales, quick delivery, and of course, decent pricing. Some of the reviews had me a little skeptical, and time will tell regarding the longevity, but so far I am pleased.
My protein powders are on the heavy side, but this little frother really gets the job done. Instead of having to use separate mixing cups (saving me on dishwashing), I just use my morning coffee cup (it's big enough) to mix my protein shake in. My husband just uses a regular glass.
Neither of us can believe the power this little thing has. We are getting smooth shakes!
Here is what I really like about it: It is powerful and mixes well; the frother is metal and not plastic; it cleans extremely easy; after making several shakes the battery has not died; can be used in glasses, coffee cups, even disposable cups (when we buy donut shop coffee); and I love the little stand which takes up barely any counter space. Less plastic, less clean-up, dependable (so far), and small, making it convenient even for travel.
I'm really glad I got this, and hope it will last. One last thing, do not turn it on while cleaning under running water. (Yes, you can laugh.)

Powerful frother with a long rechargeable battery life
Color: Black
After purchasing three of the battery operated frothers. I finally found this amazing frother. It is very powerful so you do have to be careful not to slosh liquid out of your cup when you’re using it. But I have found it helps if you rotate the frother in a stirring motion while you are using it. That really helps keep the liquid from overflowing out of the cup. It has a sleek design and is rechargeable and the charge less about two weeks.I love this one so much. I take it with me when I travel. I actually left my original one at my mother’s house the last time I visited her and have ordered another one for my house. Highly recommend.

Great Power and Creamy Foam
Color: White
This frother is amazing and has really good power. It creates creamy, smooth foam in seconds and works perfectly for iced lattes, cappuccinos, and matcha. I love that it’s rechargeable and lightweight, but still feels strong and high quality.
As someone who loves coffee, this has become one of my favorite tools for making café-style drinks at home. Easy to use, easy to clean, and looks beautiful on my coffee station.
