The AEM 21-508R Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicles restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Honda Civic SI 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 relocated to the driver-side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable red powder coated finish. This air intake system was developed to accommodate the engines factory emissions control devices including the inlet air temperature sensor and a replacement breather hose. 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 backed by AEMs 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.

    Must have this if you have an iPad.
    Fits my iPad perfectly. Makes storage of the power cord easy. It also protects the iPad when not in use.

    Perfect for my iPAD, cash, phone, & more
    Size: 12.9 inch, Color: Indigo
    I searched Amazon a few different times trying to find exactly what I was looking for. We're traveling out of country and I needed a couple of very specific things in a bag for my iPad. It has the padded space for the iPAD, then beside it is an equally sized space for whatever - money bag, etc....for me. T here's a front zipper pocket with a smaller pocket included holders for 2 pens. My time and energy paid off by purchasing this bag. The iPAD slides in lengthwise making it easily accessible along with the cash bag I'll be accessing frequently. Its qualit y, it looks very nice and its lightweight. I'm a happy camper. I recommend getting this bag. Oh, I will also carry my cell phone in the bag too.

    A Very PROfessional looking bag for all my iPRO Mobile Devices!
    Size: 13.3-14 inch, Color: Dark Gray
    Moko products usually meet my expectations and this little bag is no exception. It’s the perfect size for an iPad in a fully enclosed case. The front pocket is ideal for cords, backup charger battery, pens, notepads, iPhone, etc. We (husband and wife) are both in our 80’s and sometimes need to take our iPads to medical appointments because it’s often hard to see everything we might need to see on a regular iPhone screen. We bought a dark blue one in January for my husband to safely take his new iPad to work so he could read kindle books during his breaks. The day after I ordered it, he had to retire under VA Disability. Still, it has come in handy as we take care of paperwork, etc. I liked his so much that I ordered this gray one last week. The size, style, colors, etc make them look very professional. The bag is small enough that even I can lift and carry it. (It’s too small for use with a full-size laptop especially if it has a case of any kind.) I have the 2025 iPad Pro (M5) and my husband has the 2025 iPad (A16). We both have the 2025 iPhone 17 Pro — mine is the regular size and his is the Max. Both are in completely enclosed cases. It is a necessity to have a secure way to use our mobile devices away from home, and these bags are perfectly compatible with everything we need to carry around in them as protection for our valuable devices. The MOKO cases are stream-lined, easy to use, not bulky but padded enough to give protection. Best of all, the price is quite good for an item of this quality. At $30 @, I suspect they could possibly outlast us! They also should be easy to spot clean if necessary. I find I can keep my magnetic paper-feel screen in the inside pocket to use with my iPencil Pro, which I can store in the smaller front compartment. In fact, I will probably keep all my accessories in the bag, then just add my iPad when I need to take it with me. I’m glad we both have our own and highly recommend this if you are looking for a bag for this purpose.

    Very impressive and cute carrying case
    Size: 12.9 inch, Color: Purple Starry Sky, Size: 12.9 inch, Color: Purple Starry Sky
    I've been looking for the "perfect" ipad carrying pouch for a while now and this one is the closest I've found. I use my ipad primarily for art so I always have a stylus, a sketchbook and various odds and ends with me. My 13 inch ipad while in it's bumper case fits in the sleeve easily without the stylus attached and in the main compartment with the stylus attached. There is also enough room for an extra sketchbook/kindle/keyboard in the main part of the bag The zipper quality is nice and I like the feel of the zipper pulls. The handle on the top is very convenient. The crossbody strap is the only thing I'd be a little concerned about because the attachment hardware is plastic but it doesn't feel flimsy at all. The padding is a good amount and I think I would feel safe with my ipad in it with a less robust or even no case. Also I'm just really happy that it had some fun and cool colors available, I'm tempted to pick up a more 'business like' color in the future.
