AEM's Bosch 4.2LSU 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 wideband air/fuel UEGO controllers. These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.

Long lasting and fun
This toy has lasted longer than other octopus toys I've bought in the past. Even if a leg or two is ripped off, it still holds on.

Awesome product, but NOT sturdy
My dog LOVED this product, but unfortunately the head came off in less than a week.

Glad this toy is back
Large soft dog toy. I have been trying to buy this item for years. It apparently was discontinued, but it finally has been replaced with an even better, more durable product. I have two large chocolate labs and they have yet to gut it. It is reasonable durable, but I suppose a determined dog could eventually rip into it. I will definitely again. Large grunting noise maker in the body, and small squeakers in the arms.

Fantastic octopus
Color: Blue
This toy is everything for my 15 lb schnauzer. Tons of crinkles in each of 8 legs and squeezes easily at head. He has over 75 toys and is one of his top 5 toys now. Great size not too big. Dog see blue and yellow so a plus. Rest of colors to them are shades of black, greys and to white.

Cute and fun!
Color: Blue, Color: Blue
This was exactly as described! The head has a squeaky and the legs crinkle. I have a small dog who does not destroy her toys so I think this will last a long time. So far—she loves it!!
