Bosch Wideband 5-Wire O2 Sensor by ProSport

The newest generation of oxygen sensors are being called "wideband" lambda sensors or "air/fuel ratio sensors" because that's exactly what they do. They provide a precise indication of the exact air/fuel ratio, and over a much broader range of mixtures - all the way from 0.7 lambda (11:1 air/fuel ratio) to straight air!

The Bosch LSU 4 wideband oxygen sensor is a 5-wire sensor that reads oxygen in much the same way as a traditional oxygen sensor. but it uses the latest "planar" construction with a special two-part sensing element to measure how much oxygen is in the exhaust.

The Bosch LSU 4 wideband oxygen sensor has a response time of less than 100 milliseconds to changes in the air/fuel mixture, and reaches operating temperature of 700 to 800 degree Centigrade (1,400 degree F) within 20 seconds or less using its internal heater. This is nearly twice the operating temperature of a conventional oxygen sensor.

Features

  • Response time of less than 100 milliseconds to changes in the air/fuel mixture
  • Reaches operating temperature of 700 to 800 degree Centigrade (1,400 degree F) within 20 seconds or less

Applications

  • Can be used with PLX, Innovate systems (LM-1 or LC-1)or simply as a replacement to your stock wideband O2 sensor.

I have one of these in a larger version I picked up at the petstore. This one I do not recommend. There is a whole in the center where the pet bites down and my doggies' teeth kept getting stuck in it. If you've ever had a toy get stuck in your pups mouth, you've seen how thet go nuts trying to get it out.

Cane Corso approved
Size: Jumbo, Style: Beef
I have two Cane Corsos, One is 80 pounds the other is 120 pounds. They can seriously destroy some toys very easily. These chewies have actually lasted for over six months at this point, which is pretty much miraculous. I bought them some more just so I always had plenty of them laying around as this discourages them from getting into trouble, chewing things they shouldn’t be chewing. They walk around with these and their mouths all the time and even after all these months, the squeakers still work. These are really high-quality and if you have a dog that just destroys toy toy, I highly recommend these. Even though they’ve had these for months, they go back to them to chew on and play with , it’s also really funny because they walk around with one and hanging out of their mouth and it looks like they’ve got a stogie hanging out of their mouth. If these toys can keep the interest and survive being mauled by these two giant Destructo mutts, then they must be really, really tough. I highly recommend these for super chewers. These even a hold up to having one dog, grab each end and then play tug-of-war with it. These guys can Easily go through A cow huff every day, but these toys are still going strong

Not a chew toy
Size: Medium (VALUE 2-Pack), Style: Beef
This is not for a voracious chewer...not durable. My dog destroyed in a matter of minutes, so the cost was high compared to the time it lasted. Maybe my expectation was too high but was disappointed in this product.
