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.

Reliable Dual-Monitor Hub That Adds Useful Ports Without Extra Bulk
Style: 8 in 1 【2 HDMI + Ethernet】
Anker PowerExpand 8-in-1 USB-C PD Media Hub Dock is a very practical docking option if you want dual-monitor support without moving to a full desktop dock. The dual HDMI outputs make multi-screen setups easy, the extra USB ports handle everyday accessories well, and pass-through charging helps keep a laptop powered through a single connection. It is compact enough for travel but still feels sturdy for daily desk use. One important advantage is that setup is usually straightforward, though Mac users should know dual external displays may mirror instead of extend because of macOS limitations. Overall it offers strong value for productivity, home office use, and clean cable management.

Really solid docking station
Style: 8 in 1 【2 HDMI + Ethernet】
I’ve been using this Anker 8-in-1 docking station for a little while now, and honestly, it’s been a great upgrade for my setup. The dual HDMI ports work perfectly with my two monitors, and both displays look sharp in 4K. Plug-and-play was super easy — my laptop recognized everything right away.
The hub itself feels sturdy and well-made, and it doesn’t take up much space on my desk. I also like that it has all the essential ports I need, so I’m not constantly unplugging and replugging things.
My only small complaints are that it gets a bit warm when I’m running both monitors for a long time, and I wish the USB ports were spaced out a little more. Not huge issues, but worth mentioning.
Overall, if you want a simple, reliable docking station for dual monitors, this one is a great choice. I’m happy with it and would definitely recommend it.

Compact, Budget Friendly, Decent Functionality
Style: 8 in 1 【2 HDMI + Ethernet】
The design is simple to use, small in size and is very lightweight. The value for your money is good when compared to other usb/hdmi dock hubs. The cable that runs from the device to your PC could be longer as it can be a little awkward depending on your desk configuration.
The only problem I had was a small defect in manufacturing specifically with the ethernet port. There was an extra bit of metal casing that made it very hard to remove the ethernet connector after use and/or would scrape the plastic connector until it eventually made clearance in the plastic. It was rectified by simply removing the malleable defect with a small screwdriver. Overall it has been a good buy though and I would recommend it if you’re in need of additional monitor connectivity without breaking the bank.

First anker product that has not worked
Style: 8 in 1 【2 HDMI + Ethernet】
Updating my review - Anker reached out and provided a new docking station. I'm now a few weeks in and I've not experienced any cutting out of my second monitor. Thanks for the great customer care, Anker!
________________
I have had a great experience with most Anker products over the last 5+ years. This one is the exception. I've tried multiple (5 or 6) HDMI cables to run dual monitors off my work laptop and this cuts out incessantly from the HDMI attached to the device (monitor goes black for 2-5 seconds). My laptop runs dual monitors at work without issue. The only variable between work and home is this device. It has progressively worsened over the last 2 months to the point I have leave a review.

Good docking station - when it works
Style: 8 in 1 【2 HDMI + Ethernet】
Generally, this docking station functions well and as expected in the year+ that I've had it. The number of ports works well for my setup of 2 external monitors + camera. The connecting cable from dock to machine is short, but not an issue for me. Unfortunately it will go haywire periodically, ~ 1-2x per month or so. One monitor will display gray, or the other, or neither monitor will be detected. In my favorite case, the entire setup blinked in and out of functioning for about 5 minutes before dying completely... in the middle of an interview. I've updated drivers, rebooted, reconnected, all the things, so I've just decided that my particular docking station is lightly haunted.
