- Make sure fitment first, thanks a bunch!
- Illegal for use on vehicles required to meet California emission standards. (Do not buy it if your vehicle was registered in CA or NY)
- Cutting and welding may required, professional installation is highly recommended.
Please pay attention during usage:
1. Do not use leaded gasoline.
2. Do not run fast for a long time (open-loop control state).
3. Do not allow the engine speed to change quickly.
4. The ignition time should not be too late.
5. It wont start for a long time.
6. Do not pull out the high-voltage line for a long time to test.
7. When measuring the cylinder pressure, unplug the central control connector of the fuel pump, so that the injector can stop the injection of fuel into the cylinder.
8. When it is found that the cylinder is not working properly, it should be stopped in time for inspection and troubleshooting.
9. Avoid factors to a rich mixture, such as inadequate closing of the fuel injector, failure of the fuel pressure regulator, failure of the oxygen sensor, and failure of the air flow sensor
10. As long as the catalytic converter is used correctly, it generally does not require maintenance, so do not disassemble it casually. If it needs to be replaced, it must be matched with the engine.

Catalytic converter structureCatalytic converter composed of shell, shock-absorbing layer, substrate, carrier, and catalyst. The substrate material of the catalyst is mainly honeycomb ceramics, the structure increased the effective contact area with the exhaust gas to the most. Ceramics provide strength with lower density, the resistance of high temperature, small coefficient of thermal expansion, etc. The carrier coating is usually Alumina (Al2O3), which compatibility both well with ceramics and catalyst, and provide good specific surface area and thermal stability. And the precious metal catalyst is Rh, Pt, Pd. (Platinum Group Metals) |
Conversion efficiency with A/F (Air-Fire ratio) and T(temperature)Only at the ideal air-fuel ratio (A/F 14.7:1), the conversion efficiency of these three pollutants will be relatively highest at the same time. And the temperature is extremely important for a catalyst too, in order to maximize the efficiency of the converter reaction. Usually, the best temperature range is 400-800℃. The Light-Off Temperature is 250℃, between 250-400℃, the conversion efficiency would drop sharply. And beyond 800℃, the precious metal catalyst would be aging rapidly. |
The common causes of failureThe temperature is too high. when exceeds 1000 ℃, the catalyst in its inner layer will sinter and die, even fires. Chronic poisoning. S, Pb, P, Zn and their formation of oxide particles after combustion in the engine are easy to be adsorbed on the catalyst. Surface-area carbon. The soot emitted by the engine would adhere to the surface of the catalyst. Exhaust deterioration. aging or overuse leads to failure. Differential use. The installation and application should be strictly matched according to the engine model. Oxygen sensing failure. Ensure the oxygen sensor is working properly to achieve the best Air-Fire ratio, Oxygen sensing failure would cause lots of problems. |
About the Code P0420/P4030This catalytic converter can eliminate the check engine light on caused by code P0420 - catalyst system efficiency below threshold. Therefore, before replacing a catalytic converter, please make sure your O2 sensors still work well. Faulty sensors can cause Oxygen sensor carbon deposition, ceramic chipping, heater resistance wire burnout, internal circuit disconnection, and damage to your fuel economy as well as the service life of the converter. |
