If your engine is V6 / V8 / V10, you may need TWO O2 Sensor Simulators!!!

What's the Benefits? 

Improve fuel economy and performance, eliminate CEL

If you are using racing header, straight pipe, or there is simply something wrong with your catalytic converter, this is the product for you. You may have CEL on with P0420 and / or P0430 code.    

Without the simulator,  the car is operating in safe mode and performance is greatly compromised. Adding this simulator will fully unleash the potential of your aftermarket parts, usually more than 30HP!!!

Advantages of our product 

Compared to other vendors, our oxygen sensor simulator is probably the least expensive you can find. Even at such low price, quality is never compromised. Our simulators are far superior to competitors.    

1. We use intergrated micro controller to fabricate genuine O2 sensor simulator. The sim will generate exactly the same wave pattern as your factory O2 sensor does.   

2. We use surface mount technology (SMT). Surface mount electrical components are  less prone to external damage than through-hole ones and offer far better reliability.

3. We use batch fabricated printed circuit board (PCB). Thanks to the compact size of surface mount components, same functionality can be achieved by our truly tiny (1" x 1") PCB. Compare to hand-made products, our PCB can sustain more heat cycles, vibrations and severe environment.  

4. We use highest quality potting compound and box to package our products. The best potting compound can seal your oxygen sensor simulator to water, dust, and acids.
