The K&N Performance Airbox is designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. Replacing the restrictive factory air filter and air box allows your engine to inhale more air than with the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. A fully enclosed injection molded air box connects to the factory air intake hose. The removable lid provides easy access to the filter when cleaning is required. This performance air box is relatively easy to install. The required tools are commonly available and it uses the previous air box space. These air box systems are built to last for the life of your vehicle and they're backed by K&N's No-Hassle Lifetime Limited Warranty. Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Check the K&N catalog or website for vehicle applications and specific TUV status for each vehicle and air intake.Shipping Notes

Great for wide feet

Easy on and off. Great for wide feet. I love that the velcro is just across the top and doesn’t loop around.

Cushiony and lightweight sneakers!
Size: 5.5 Toddler, Color: Gold/Rainbow, Size: 5.5 Toddler, Color: Gold/Rainbow
The shoes are excellent quality! I was worried that the soles would be heavy since they are a little thicker than other toddler shoes, but this is not the case. The shoes are lightweight and run true to size. They were a little hard to put on the first two times and I thought, "Oh no, they must be too narrow." However, after my toddler wore these for a few hours each time, they stretched out and I checked her feet and did not notice any signs of discomfort, such as impressions on her feet from the shoes and/or redness. Toddler walked "normal" and even ran in these. The style is supercute (gotta love the subtle sparkles) and athletic and they appear to give her a lot of support. I can't speak to durability as she has only worn them for a few weeks but so far, they held up well and I have no issues with the velcro. I am glad they softened and stretched out after a short time of wear and they have plenty of cushion! Overall, these are great and no complaints here. I highly recommend!
