But the reason the first ones quit, was the wires were mouse eaten through. Turns out you need continuity for them to function. Repaired wiring and installed new sensors and no more trouble code. Only took 4 hours to get to them under the intake manifold. And 3 hours to replace manifold. Your time may vary.

High quality, fast shipping, it’s Bosch, built to last. I changed the old ones as a preventative maintenance after 26 years.

What is not to like? I bought this for my 2006 Mercedes C280 W203, it worked perfectly and looks exactly like the original. Easy to install if you follow directions to remove the electrical harness, fuel injection rail and intake manifold. Once these are lifted up, the part goes under where the intake manifold was seated. Easy to pop off the old one and slip the new one on, then reverse the order to replace everything back. You are now ready to go!

Used it to listen into my engine while tuning and it worked flawlessly. It’s a wideband knock sensor so it picks up all frequencies and the ECU is just tuned to pick up certain once.
