The AEM 21-823DS is a twin intake system designed for some Infinity Q70 models. The factory layout of this vehicle has individual throttle bodies for each bank of cylinders so each side has its own air intake system. This AEM air intake system replaces both the left and right factory air box, tube, and filter. This system includes the heat shield, intake tube, and AEM dryflow air filter on both left and right sides. The cone shaped AEM Dryflow air filters are 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). Both factory MAF sensors mount directly on the intake tube. The heatshield also has a rubberized edge trim to better isolate air from engine bay heat. The air intake system 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.

Great base to add patches to
Size: X-Large, Color: Black
I've bought this jacket twice now (lost the first one...). Great base for my DIY patch jackets. I buy an XL even though it's a size too large for me. It's a standard denim jacket, not much to write home about. Good pocket size, and I appreciate the functional chest pockets.

good stretch
Size: 10 Long, Color: Dark Wash
Honestly, these are one of those surprisingly good basics—especially for the price. The biggest standout is the stretch. They’re really comfortable and move with you, so they don’t have that stiff “jeans” feeling. They hug your body in a flattering way without feeling too tight or restrictive, which makes them easy to wear all day. The mid-rise fit is also a sweet spot—not too low, not too high—so they’re super versatile with different tops. What I liked: Very stretchy and comfortable (almost feels like jeggings, but still looks like denim) Flattering skinny fit through the legs Easy everyday jeans—work, errands, going out Great value for the price What to know: Material is on the thinner side (more comfort than “structured denim”) They can lose shape slightly after a full day of wear Not the most durable long-term compared to higher-end denim Final thoughts: These are perfect if you want cute, comfortable, affordable jeans you can throw on with anything. Not premium denim, but for everyday wear—they definitely get the job done and are worth having in your rotation.

Amazon Essentials Women's High Stretch Jeans
Size: 14, Color: Iced Blue Light Wash
Amazon Essentials Women's High Stretch Jeans receives positive reviews from me for their significant stretch, comfort, and flattering fit. The jeans are great for everyday wear, they feel soft and thick yet move well. Although some folks find sizing inconsistent, occasionally needing to size up or experiencing a slightly odd fit in certain areas. They're praised for looking good, offering good value, and being versatile enough for various occasions. Sizing can be hit-or-miss for some, but not for me.

Size down.
Size: 8 Long, Color: Iced Blue Light Wash
They are high stretch so I would size down from your usual size. I have bought size 10 in their brand and noticed the two previous I've purchased before this one were loose. So when I purchased this one I sized down and they fit good to me. I got long so they are LONG. And the regular would probably fit at your ankle or above. The only reason why I didn’t give it 5 stars was bc I don’t feel it mid rise to me it feels like high rise but I don’t feel them uncomfortable and also THEY ARE NOT SKINNY JEANS. They are straight leg and a tad bit loose so if you want stretch and skinny jeans these are not the ones for you. I only bought them thinking they were like the picture but it’s false advertisement.
