AEM's Bosch 4.9LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM Digital Wideband UEGO Air/Fuel Controller Part Number 30-4110.

One of the best deals available!
Color: White, Size: 2 Pack
Extremely sturdy, good looking and easy to install. I have a couple of dozen feet of assorted lengths in the kitchen, bedroom, living room and foyer. Holding all sorts of antique clocks, audio equipment and cooking stuff from my flours and assorted cornmeals to cases of powdered “lemonade”.

Mounting system doesn’t align on one of three shelves.
Color: Walnut, Size: 3 Pack
Nice shelves. Install was super easy except on one of the three shelves. The main mounting shelf holes were off so the shelf will not slip onto horizontal mounting poles unless I modify the shelf. So a 20 minute job becomes a two hour job. The mounting system does appear very sturdy just not aligned.

Great quality
Color: Rustic Brwon, Size: 16in
Hassle but they work great. I love the color, the thickness and quality. They do have some weight but in my opinion, I prefer that. Right now the four shelves are holding up my WiFi routers and remotes. Will buy again

Good quality shelves
Color: Walnut, Size: 24in, Color: Walnut, Size: 24in
These shelves are gorgeous in person. Yes, they're darker than the listing pics, but I actually prefer it. The grain is beautiful, they came well-packed, and mounting them was no trouble at all. Now I've got display space that feels both stylish and practical. Definitely worth it!
