K&N 57i Series induction kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provides even more airflow at lower restriction than a K&N O/E replacement filter which is limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Series Intakes are not legal for use in California and other US States adopting California emission standards.- Guaranteed to increase horsepower

Reliable and Versatile Adapter for My MacBook Air
I have a 13-inch MacBook Air, M4, 2025, and I use it for everything: work, watching videos and series, and occasionally gaming. I also regularly attend court hearings and professional meetings through Zoom, Google Meet, and similar platforms, so I cannot afford connection issues.
This adapter, especially with its LAN port, has been very useful. It gives me more confidence when attending hearings online because I can rely on a stable wired connection. It also works well while connecting other devices, such as microphones or pen drives, which makes it very versatile.
The finish and materials feel solid and high-quality. I used to have a white plastic adapter from another brand, but it ended up changing color with use. This one stays cleaner, looks more professional, and is easier to keep in good condition.
It is easy to carry, practical, and very efficient.

Good quality product
Good value for the price I paid. I have all the slots in use and it works fine. It really helps increase the reading and network speeds, if (like in my case) I have to use both ethernet and/or wifi antenna for my company laptop.
It is slim, sturdy, discreet and I like the main cable that connects to the PC is very flexible like a cord.
Very happy with it.
The only downside is that it gets very hot, I don't know why, but other than this, it really meets my expectations!

One cable does it all, rock solid Ethernet and great 4K output
This hub has simplified my desk setup considerably. I plug it into my MacBook and instantly have Ethernet, 4K HDMI, two USB-A ports, and 100W charging all from one connection. The Ethernet is Gigabit and the speeds are as fast as plugging directly into the router. The 4K HDMI output to my monitor is clean with no flickering. It runs slightly warm during extended use but nothing alarming. Build quality feels solid and UGREEN has been consistently reliable in my experience. Worth every penny if you need to expand a USB-C only laptop.
