Most COMPLETE and COMPACT Air/Oil Separator on the market!
An Air/Oil Separator has one job, remove the oil from the engine ventilation system so the oil does not get sent through the intake system.
The GrimmSpeed™ Air/Oil Separator for Subaru vehicles has a unique design that allows you to maintain your PCV Valve while separating the oil out of the crankcase and head ventilation air! Our AOS will allow your engine to run more efficiently due to the separation of oil from the intake system. When there is oil in your system, the result is 1) reduced fuel octane 2) higher chance of engine knock(detonation) 3) worse emissions 4) higher oil consumption. Our Air/Oil Separator will help all of these problems.
In typical GrimmSpeed™ fashion, we have made a very compact unit that packs a powerful punch(and looks good while doing it)!
No more having to check/empty your catch can and refilling your oil. The GrimmSpeed™ AOS coalesces oil without using a mesh media. Mesh medias can cause contaminates to collect and build up resulting in possible sludge. Our AOS is self maintained so you can just sit back, stop worrying, and enjoy driving your car!
Please note this product is designed to combat factory amounts of blow by. If you have a built motor or are experiencing abnormal amounts of oil consumption, this product may not work for you.
Air/Oil Separator FAQ:
Q: Is this beneficial on a street car?
A: Yes. Even in stock form, you will experience oil going through your intake system. If you have ever looked in your intercooler piping you will notice a bunch of oil build up on the inside, our AOS takes care of this problem.
Q: I've heard about the milky oil substance in cold climates when using an AOS, is that relevant?
A: During our testing here in the frozen tundra of Minnesota we have only noticed very minimal milky substance from the AOS. Condensation is allowed to collect on the inside of the core but will evaporate when the engine gets up to running temps.
Q: Why choose the GrimmSpeed™ AOS over other AOS products?
A: The GrimmSpeed™ AOS allows you to separate the vapors from both the heads and the crankcase. Others on the market only allow you to separate the vapors from the head. Also, our AOS allows you to retain the OEM PCV Valve. Being that it allows you to do both of these things at the same time makes it the most complete AOS on the market.
Q: How will this AOS increase my octane?
A: When the oil vapors are mixed into the intake system, it effectively lowers the octane which can cause detonation. Installing our AOS will eliminate the oil vapors in your intake system thus eliminating the loss of octane. On modified cars this let's you get more aggressive with your timing/boost maps and will allow you to make more power!
Q: Do I need to carry around a 19mm socket to open it?
A: No, we have sized the cap nut to be the same size as a lug nut. So as long as you have a tool to take your lug nuts off(which you should always have in your car), you will have a tool to open the AOS. On a proper running system you shouldn't need to open the AOS very often.
Q: How big is the unit compared to the oem oil cap? I'm running a FMIC and need to make sure it will fit
A: We created it so it will work perfectly with a FMIC as well. The body of our AOS as the same diameter as the oem oil cap.
Q: What models will this fit?
A: Our will fit EJ series turbo Subaru engines

Nice protector cover, quiet and comfy - best for THICK mattresses
Color: 3 Navy Blue, Size: Full
I liked this pad immediately as fabric cover has nice quilting (just slightly puffy), and touch feel and feels substantial enough to hold up over time. I’ve ordered a few different brands of these and they were crappy, insubstantial pads I did not think would hold up to more than a couple washings.
My biggest complaint and it’s due to my own lack of experience buying these in the new world of skillions of mattress thickness choices is that (A) the side panels / elastic pockets are HUGE and will never be secure on anything thinner than a 12” (or thicker!) mattress; and (B) I thought I was buying an ENCASEMENT cover pad which this is not. I’m blaming that on Amazon because I specifically input “encasement” in the search and their F’ing search algorithm does whatever the heck it wants and if you’re not paying nit-picky attention you get stuff you don’t want. (Or you waste time sorting out the ones you didn’t want to see in the first place!)
That said I am seriously considering keeping this (depending on late arrivals of competing covers) as I’m certain this will be comfortable and as quiet as these waterproof covers get. It’s a nice cover.
UPDATE: it’s a couple weeks later and I’m reporting I did keep it and am happy to have done so. It installed more securely than anticipated and is as comfortable as I thought it would be. I’ll try and update again when I have time to resize pics and show how much my cat enjoys it too:)
UPDATE#2: in review I noticed that the 1* reviews were on about nasty liquids leaking through - I haven’t had any large scale events to gauge but I can see how those reviews could be valid. I should report out of EVERY type of these “nice” noiseless “waterproof” pads I’ve got I think every one of them probably could have the same fault. In other words though I use and really like this cover I also purposely use an encasement style mattress protector (you know the put it in a bag w/zipper kind and a pain in the a** to do so kind) to avoid the complaints in the 1* camp. These mattresses are just too costly and spongelike to NOT protect them completely so I appreciate their frustration that things leaked for them. In my choice to keep this I did so because a) it most probably is pretty waterproof & is definitely quiet & comfy; b) it’s pretty easily washable; and c) because most of the encasement protectors are of more “crinkly” material than this (at least the ones I’ve seen so far - maybe the super expensive ones have figured out how to be perfectly waterproof without crinkle) and by using this nice top protector I put a layer on top of the crinklier encasement and everything just ends up much better with no noticeable crinkle. Figured I say this to help detail 1* vs. 5* because right!? how can one thing be so great and when you turn around then be so terrible… just sayin. (& I did not change my 5* rating😎)

⭐⭐⭐⭐⭐ Excellent Protection and Comfort — A Mattress Protector That Really Works!
Color: 3 Navy Blue, Size: Full
The BEDLORE Waterproof Mattress Protector, Full Size Mattress Pad with Deep Pocket (6″–15″) has been a fantastic upgrade to my bed setup. If you’re looking for reliable protection without sacrificing comfort, this protector delivers on every promise — and then some.
🛡️ True Waterproof Protection
This mattress protector does exactly what it should — it protects. Whether it’s accidental spills, pet messes, or everyday body sweat, the waterproof barrier keeps everything from reaching your mattress. I’ve tested it with a few wet spills, and the liquid beads right up on the surface, giving me peace of mind that my mattress will stay fresh and clean for years.
🛏️ Soft and Comfortable Sleep Surface
Unlike some protectors that feel stiff or noisy, the BEDLORE pad is soft, quiet, and comfortable. You barely notice it’s there, and it hasn’t changed the feel of my bed at all — it just adds protection while letting the mattress feel like my mattress. Sleeping on it feels smooth and cozy rather than plastic or crinkly.
📏 Deep Pockets Fit Perfectly
The deep elastic pocket is one of my favorite features. It securely fits my mattress, which is on the thicker side, and stays in place even with nightly tossing and turning. The coverage from 6″ to 15″ means it fits almost any standard full mattress comfortably without slipping off or bunching up.
👍 Breathable & Quiet
Despite being waterproof, this protector remains breathable, so I don’t wake up feeling too warm or restricted at night. It’s just the right balance — protecting without interfering with airflow or comfort.
💪 Easy to Care For
Machine washing and drying are a breeze — it comes out clean and stays soft after every wash. I appreciate that it retains its shape and waterproof performance even after multiple washes.
✅ Final Thoughts
Overall, the BEDLORE Waterproof Mattress Protector is a well‑made, comfortable, and highly effective mattress pad that offers great protection without the unwanted stiffness some other protectors have. It’s a smart way to preserve your mattress investment while still enjoying a comfortable night’s sleep. I’m very happy with it and would absolutely recommend it!
