The AEM 21-750 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 Audi A4 and A5 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 location and can optionally be protected by an AEM embossed heat shield which is designed to reduce intake air temperature and increase horsepower. 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.

Comfy but wear quickly
Size: Large, Color: Organic Cotton 2 (5 Black)
These are perfect for every-day wear and i find them super comfortable. Mine are starting to tear and fall apart, which is more quickly than my other underwear, but I think its worth it for the price and comfortableness. I'll just replace them or repair them :)

Soft and True to Size
Size: Medium, Color: Organic Cotton( 5* Multi)
Comfortable and true to size these boyshorts are perfect. It's great to know it's safe material and organic and it holds up well in the wash. I would definitely buy again.

Comfy cute undies
One of the first things I switched out when I went on my non toxic journey, I really feel like they help my hormones balance and they’re so comfy

Falls apart after 5 wash cycles
Terrible. Do not buy. Only last 5 wash cycles before unraveling and falling apart. Also, uncomfortable as hell.

Disappointing, durability despite softness
Size: X-Large, Color: Organic Cotton 2 (5 Black)
I really wanted to love these underwear. The material is incredibly soft and has a nice, thick feel that seemed promising at first. Unfortunately, the quality doesn’t hold up. After about 12 washes, the seams started coming apart, and within two months, I had to throw away two of the five pairs because the fabric separated from the waistband. It’s frustrating because they were so comfortable initially, but the poor stitching makes them a bad investment. I wouldn’t recommend these unless the company improves their durability or you’re OK with losing One or two pair of the five
