Description

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.

          Quality product but sold on Amazon cheaper with different seller.
          Size: Medium Size 2, Color: White-Blue
          The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.

          absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
          Size: Large Size 3, Color: White-Blue
          I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

          Perfect for keep-away
          Size: Large Size 3, Color: Red-Blue
          I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.

          70lb dog loves this kind of ball!
          This is my dog's favorite style of ball! I have purchased others before, first from a local farm supply store and then others from Amazon, and this ball is of comparable quality to the others! The multi-tag design is great for my dog who love to tug and also to throw toys for himself. It's still inflated for now, but I'm under no pretense that it will stay that way forever. Part of the enjoyment my dog gets from his toys is in their destruction, and while we haven't hit that phase yet I'm sure it will come. This ball is great for medium to large-ish dogs who enjoy a ball that is kicked, thrown, or tugged!

          So much fun
          My dog is obsessed with this. It comes deflated and you have to pump it but it only takes like 30 seconds to pump. And it comes with the pump which is so convenient! It's nice because you can leave it a tad deflated so your dog can grab onto the ball part if you want. My dog has bitten it a ton and it hasn't popped or deflated yet so it seems sturdy. I like that there are multiple handles because not only does it make it easy to play tug o war but also then you can have multiple dogs playing with it at once. Has held up good over the past week and a great source of entertainment! My dog is about the size of an aussie for reference and it is perfect size for him and small enough for him to carry.
