It is highly corrosion and wears resistant.
By using, it can help to improve exhaust gas velocity, save horsepower and torque.
Great emissions control, high efficiency and work efficiently.
Installation:
1. Lift the vehicle so that the chassis is clearly visible.
2. Remove the oldthree-way catalytic converter and its pipe section.
3. Install new the three-way catalytic converter and smear the bolts with anti-sinter lubricating oil.

Q: Can the three-way catalyst directly change the carrier
A: It is very difficult to directly change the carrier, and it is recommended to replace the whole section
Q: How to know whether the three-way catalytic converter can work properly?
A: Check whether there is a fault code after starting the vehicle for a period of time, and pay attention to observe whether there is a fault code during subsequent driving
