A high-density polyethylene (HDPE) rotationally-molded tube helps increase the volume of airflow to your engine, and provides a guaranteed increase in horsepower and torque. These systems are paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media. The oversized, conical design allows you to go up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from the high temperature of your engine bay, and the entire system can typically be installed in less than 90 minutes.

Size up, great quality
Number of Items: 3, Color: Grey/Blue/Sea, Size: X-Small
I ordered the XS and I have to say they run small. They fit my 2 year old not 6 year old. So size up. But honestly love the quality of Amazon essential shirts. I buy these for my kids pjs they are very soft

Comfy and Cool Shark Shirt
Number of Items: 1, Color: Ivory Sharks, Size: X-Small
We live near the beach, so I love finding ocean themed clothing for my little grandson. He loves this colorful swimming sharks crew neck t-shirt. He says it looks "cool." The cotton blend material is soft and and gentle against his skin. It's breathable and slightly stretchy. . The stitching is straight and consistent with no loose threads. We have fun talking about the different sharks, and the shirt looks great with his everyday jeans, joggers, or shorts. If you want some growing room, I suggest ordering a size up. The 5T is just a little long and roomy in the shoulders for my grandson who usually wears size 4. For laundering, I turn the shirt inside out and wash on cold to preserve the print. I haven't noticed any shrinkage or fading. I've been drying it on a warm setting (though cool is ideal), but I’m pretty careful not to leave it in the dryer too long to avoid wrinkles. He's been wearing it since his birthday in February, and so far, it's kept its shape, and seems to resist stains. If you have a little one that loves sharks, this check out this comfy ocean themed crew neck.

Nice quality for some basic, essential tees. The ratio cotton to spandex makes it very comfortable to wear. Great value.
