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.

          Excellent customer service and quality
          Size: Super King, Size: Super King
          Update: since my original review the company has reached out to me and apologized for the quality of the comforter i received. They replaced the comforter with a brand new one and didn't make me send back the old one either! This new one is great quality so i am very pleased. The comforter is super comfy and not too hot or too cold. It has some weight to it which i love because it makes it so much more cozy without making me too hot. I got the super king size and I love how big it is. My husband and i don't fight over the covers anymore. With this new comforter and the way they handled things i give this company and product 5 stars and would highly recommend this to anyone! Well, I just opened this comforter and already im finding issues. There are strings coming out and at least 2 stains I've found so far. Not sure if I should return this or what as I'm sure it would be really hard to fit this back into the case. Wish this was a better experience. This was very expensive too, so very disappointing.

          Love this comforter.
          Size: Queen
          Super comfortable and light and well worth the price. Excellent quality that I didn't think I'd find again. And without the dreaded returns of trying something and it not right. It feels like the same one I bought in 2007 at BB&B on Christmas Day for half off and that was $250. So normally a $500 comforter and as a matter of fact I still have it although the feathers are kind of falling out. I'll probably just need to take it to a seamstress and have her resell a few things but I'm still keeping that as I am going to keep this. Incredible feel and very warm for an L2. The design is great. I haven't washed it yet but on order to fluff it I basically put it in the dryer for an hour on delicates with no heat. It did come sealed in a small box but it was absolutely perfect after an hour on fluff with no heat. I will end up buying another one when I get a king size bed. All I need now is a duvet that feels just like this comforter. There was no scent as some people mentioned. It smelled fresh right out of the box.

          Update: replacement comforter is much better… really impressed with this small business
          Size: Palatial King
          Update: The comforter on my bed is now everything I hoped for: fluffy, warm, and wonderfully cozy. Getting here was a two-part story, and it’s the happy ending and the fantastic service that created it that I really want to share. I’ll be honest, my first comforter was a letdown. It arrived flat and thin and just never really… fluffed into the cozy cloud I was hoping for. I was pretty frustrated, which is why I left my original review. But then, something really nice happened. The company actually reached out to me directly. They were so kind, listened without getting defensive, and genuinely wanted to make it right. They sent a replacement, no questions asked, and the difference has been night and day. This new one is exactly what I’d imagined. It has a real, fluffy loft, it’s softer, and after letting it settle, it’s become the full, warm, and comfortable comforter I wanted from the start. My quick takeaways: · A small business that stands behind their work. This meant a lot. · Customer service was top-notch kind, FAST, and professional. · The replacement is clearly better quality: fuller, softer, and warmer. · It’s a completely different (and better) experience than the first. I really value when a company just focuses on fixing things. The way they handled this completely changed my perspective. While the first one missed the mark, their response and the quality of the replacement have made me a happy customer. I’m glad I gave them the chance to make it right, and I’m finally cozy under the comforter I was hoping for.
