The AEM 21-732C Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Subaru WRX models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal.

Worth the money
Size: Queen (U.S. Standard), Number of Items: 2
So these pillows are for sure hotel pillows, great filling quality, support(not so much), no odor, they are worth the money, soft but just not the support I was looking for.
Nice fluffy, hotel pillows

The best!!!!! Don’t let the price fool you.
Size: King (U.S. Standard), Number of Items: 2
I don’t know how much money I’ve spent over the years trying to find the perfect pillow. I ordered these to use only as decor on my bed with some fancy pillow shams I had ordered and guess what- they’re my very favorite pillows I’ve ever gotten for sleeping. How in the world is that possible? So I switched my expensive pillow to my fancy sham and sleep on this every night. Buy it right now!

Impressive Set of 4 King Pillows – Comfort Meets Quality

Impressive Set of 4 King Pillows – Comfort Meets Quality
I recently upgraded to this 4-pack of king-size pillows (20 x 36 inches), and they’ve been a fantastic addition to the bedroom. Certified by Oeko-Tex, they’re suitable for all sleep positions—whether you’re a side sleeper like me or prefer your back or stomach.
The feel strikes a perfect balance between soft and supportive. The microfiber filling cushions your head and neck without going flat, so I wake up without the usual stiffness. They bounce back quickly after use and keep their shape well—just give them a quick fluff when needed, and they’re good to go. They do need about a day to fully expand once unboxed, but that’s expected.
The design also deserves a mention. The subtle stripe pattern gives the pillows a clean, upscale look—definitely not your average basic pillow. They’d make a solid gift, too.
Cleaning is easy: toss them in the washer on a gentle cycle with cold water, then either air dry or tumble on low. No hassle.
If you’re looking for a dependable set of king-size pillows that feel great and look sharp, these are worth it.
I also took a picture of it next to a standard pillow so that you could see the difference in the size from King to standard. Hope that helps, overall definitely buy these pillows if you are hesitant there is no need to be, these pillows are perfect in my opinion

High End feel.
Color: White, Size: Queen (Pack of 4)
I bought this because I needed to replace old pillows. After using it for a few day I liked that they stayed fluffy and cool all night. My guests loved them too! The quality feels high end. I would recommend it for anyone that likes high end feel without the the high end price.
