Dinan High Flow Drop-in Replacement Filters are a direct upgrade to your factory intake system and will instantly provide better flow to assist your engine in achieving maximum performance and efficiency! While factory paper filters function admirably, they can be restrictive to performance goals given the material used. They also require being replaced numerous times during the lifespan of the vehicle, which can add up to a substantial amount in maintenance costs. Limited performance and increased maintenance costs are never ideal but can be resolved effectively and economically in the case of filters. Dinan High Flow Drop-in Replacement Filters are constructed of 4 layers of cotton gauze that allow better flow and less pressure drop than the stock media. This equates to the engine not needing to work as hard to make the same, or more power. Additionally, the use of oiled cotton media means that the Dinan filters are washable/re-usable while still retaining excellent filtration and ensuring your engine runs clean for the duration. When upgrading to a complete Dinan intake system for best performance, is not available, possible, or within the budget, Dinan High Flow Drop-in Replacement Filters have you covered! General D401-0039 Filter Dimensions: 267mm x 212mm (10.51" x 8.54") Compatible OEM Part #Cross Reference: 13717602643, 13718616909
Features:
- Less restrictive and better flowing than stock allowing maximum engine performance and efficiency
- Direct replacement for stock air filter
- 4 layers of proprietary high flow oiled cotton gauze material for exceptional filtration
- Washable and reusable for the life of the engine
- Quick and easy installation

They are comfortable!
Size: X-Large, Color: 2 Pack - Navy
I really like them. Pockets are very helpful and the size was right for me eventhough it was suggested a size bigger. Washed both already and noticed no shrinkage. Very comfortable and the length is just above the knees. Great for hanging about, in the gym or even a trip to the store.

BIG GIRLS LOVE 'EM TOO!
Size: 3X-Large, Color: 2 Pack - Black
I am a plus size gal. I was looking for some sleep shorts, but all the ones for us plus size gals were so short I may as well not have been wearing anything. I decided to look in men's shorts, and found these. They are nice and long, and the material is nice and soft. Also, unlike the women's shorts, the pockets in these are nice sized, big enough for my phone and then some. There's a drawstring, but the elastic in these is plenty to keep them up and riding at my waist, where they're supposed to be, without having to tie them. Typically I wear a 2X, but I purchased these in a 3X because I like a little more room in my PJ bottoms, and they fit great. The only thing I don't care for necessarily is that the elastic waistband is just a smidge scratchy, but after wearing them a while I found it didn't bother me. And the price is pretty good for two pairs - much cheaper than women's plus shorts.
I liked them enough that I came back and bought 4 more pair!

Comfortable and stretchy shorts with pockets!
Size: XX-Large, Color: 2 Pack - Black, Size: XX-Large, Color: 2 Pack - Black
For the most part, I've exclusively worn pants/jeans/slacks since my teens, I'm pretty sure that I've worn a skirt or dress on only 2 occasions in my life, and the skirt part was ankle - floor length those 2 times... Just to paint a picture for anyone reading my review knows how serious I am about hiding my almost reflectively white legs. At least up until I moved from the West Coast all the way to Oklahoma. Not only did I realize that I've taken California/PNW weather for granted all these years, but I quickly learned that I would now be wearing shorts every chance I get in this heat.
These shorts aren't made with a heavy type of fabric, they are stretchy and lightweight, and they even have pockets! My wardrobe color pallet is mostly just black or slightly different shades of black, so of course I got these shorts in black. Plus Fruit of the Loom has been a known name brand for as long as I can remember. These are a great value for the money, great quality so far, and the waist is easy/self-explanatory to adjust. I would like to point out that the tie string in the waist somehow got tangled with a stray string or tie string attached to something else in the same load of laundry I put the shorts in. I ended up having to cut off the part that was frayed from getting tangled, so I suggest that the tie around the waist of theses shorts should be knotted/tied together to hopefully avoid the tie string from fraying in the wash or something.

You get what you pay for
Size: 3X-Large, Color: 2 Pack - Black
These are certainly comfortable, and the material itself is decent. However, the material is thin and therefore prone to puncture if you are not careful. The biggest issue is the drawstrings are very poorly sewn in, and have broken out on every pair I have purchased. Instead of being a solid loop that ties in the front, the ends are sewn in the back. The fit is true to the size listed, as long as you are okay relying exclusively on the elastic waistband. They are somewhat acceptable for the price.
