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.

          Fun while it lasts…
          Color: Pink, Style: Grunt Sound
          Fun while it lasts. Doesn’t last very long. This is our third one and last maybe a few weeks. The part that makes noise comes detached inside which causes to toy to no longer make noise, but also can be dangerous if it comes out.

          Great alternative to the grunting pigs!
          Color: Pink, Style: Grunt Sound
          We go through A LOT of dog toys at my dog based business. The grunting pigs are super cute, but they are also super fragile. It is incredibly easy to dislodge the squeaker. (Grunter?) These are certainly not robust chew toys, but the squeaker is about 30% better at staying put than that of the pigs. It's also smaller, so it's easier for the smaller dogs to play with. These are a new favorite! Update: August, 2024 I bought an orange hedgehog. Amazon won't let me review that separately so I had to add to my sheep review. The orange hedgehog is only 3 stars. It is made of a harder plastic than the bear and the sheep. It also has a standard squeaker, not the grunting of the bear and sheep. But harder plastic DOES NOT mean that it will withstand an aggressive chewer! If your dog likes to "kill the squeaker" they will be able to do so in minutes! This IS NOT a chew toy! If you are looking for a toy for an aggressive chewer, look at the Orbeez line from Outward Hound. The other thing that makes me less enthusiastic about the orange hedgehog is that the yellow paint started flaking off immediately. I will have to scrub it all off because it looks terrible! The dogs don't care, but their owners sure do! I haven't had that problem with the sheep or the bears. The orange hedgehog is almost like it's from a completely different company!

          Great find for my dog!
          Color: Hedgehog, Style: Big Squeak Hedgehog
          This is a Big squeaking toy And has become a favorite of my dog. He is a big chewer but he won’t chew at this one he just carries it around and plays catch with it. I believe the little spikes keeps him from heavy chewing on it! Great find for us! But it is a loud squeak!
