K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.- Guaranteed to increase horsepower
- Designed to improve throttle response and engine sound

No elastic around the thighs is kinda nice!
Size: 9, Color: Cotton Stretch - Colors May Vary
Great undies! They fit good and the fabric is comfortable. Only thing is that the legs tend to ride up/bunch up with pants on. I got them for post surgery comfort and thats what I got.

Soooo comfortable
Size: 11 Plus, Color: Microfiber - Colors May Vary
Easy on/off because they really do stretch but return to shape. Fit is close to the body but not tight. Love that there is no elastic binding around my legs. Clothes glide over them because they are super smooth. Might never buy another style again.

These were such a RELIEF during a shingles outbreak!
Size: 10 Plus, Color: Microfiber - Colors May Vary
I developed shingles on my abdomen and spent a few days commando because I was in so much pain and couldn’t stand anything against my skin but a nightgown. I had a drs appointment and was agonizing about showing up in a nightgown and bathrobe at the office. Then I I remembered my grandma used to wear boy leg high waisted undies so looked for something similar. These underpants by Fruit of the Loom were inexpensive and seemed to be similar to what I thought might work, so I ordered a four pack. They were very reasonably priced and when they arrived were of very good quality and well made. They were snugger fitting than I had hoped but were very very soft for tender areas on my abdomen. As it was, the snugness was comforting as they stay in place and act as a barrier between the sore rash areas and light clothing. I’ve never experienced the discomfort of nerve pain from wearing clothes andI’m so glad I happened on to these. I’m on the mend now but still wearing these as I’ve developed some neuralgia and these continue to keep me comfortable.

annoyed
Size: 8, Color: Cotton Stretch - Colors May Vary
i purchased the boxer brief. they fit perfectly. they are fairly soft and seemingly comfortable. not too thin or too thick, good for breathability. my biggest issues are the stitching being poorly done, making me worry the longevity will be lacking and the label stating “do not use fabric softener”.
the reason i am annoyed though, is the images show pink and gray colors only, which is what i was hoping for, or at least colors only. i understand all multipacks are marked “colors may vary”, but for the love of god, stop putting white pairs in these packs. white, nudes/neutrals, and black should be sold separately in their own packs. i do not want ugly old timey white underwear. i wanted colors, any colors EXCEPT white! i would however, have LOVED an all black only pack!
